Grand Theft Auto V remains one of the most iconic open-world action-adventure games ever created by Rockstar Games. With three playable protagonists — Michael De Santa, Trevor Philips, and Franklin Clinton — the game delivers an unforgettable narrative filled with heists, drama, and explosive action. This comprehensive walkthrough guide covers every main story mission from start to finish, helping you navigate through Los Santos and Blaine County with confidence.

1. Introduction to GTA V's Story Structure

GTA V features approximately 69 main story missions spread across three interconnected storylines. The game takes place in the fictional state of San Andreas, primarily in the city of Los Santos (based on Los Angeles) and the surrounding rural area of Blaine County.

What makes GTA V unique is its character-switching mechanic. At various points during the game, you can switch between Michael, Franklin, and Trevor, each bringing a unique perspective and skill set to the narrative. Missions are assigned by various characters throughout the world, indicated by colored initials on the map:

  • M (Blue) — Michael's missions
  • F (Green) — Franklin's missions
  • T (Orange) — Trevor's missions
  • H (White) — Heist preparation and execution missions
  • Other colored letters — Missions from supporting characters like Lester, Dave Norton, and others

Understanding Gold Medal Requirements

Each mission has optional objectives that, when completed, earn you a Gold Medal. These requirements range from completing missions within a certain time to achieving specific accuracy percentages or performing special actions. You can replay missions from the pause menu to attempt gold medals after your first completion.

2. Prologue Mission

Prologue – North Yankton Bank Robbery

The game opens in 2004 with a bank robbery in the snowy town of Ludendorff, North Yankton. You play as Michael Townley alongside Trevor Philips and their associate Brad Snider. This tutorial mission introduces you to basic movement, shooting mechanics, and cover systems.

Key objectives:

  • Take the hostages inside the bank
  • Place the explosive charge on the vault door
  • Collect the cash from the vault
  • Fight your way through police to the getaway car
  • Escape through the railroad crossing

The prologue ends dramatically with the crew being ambushed, setting up the events that unfold nine years later in Los Santos.

3. Franklin's Early Missions

Franklin and Lamar

The first proper mission introduces Franklin Clinton and his best friend Lamar Davis. You are tasked with repossessing two sports cars from a dealership. This mission teaches driving mechanics and introduces Franklin's special ability — the ability to slow down time while driving for precise maneuvering.

Repossession

Franklin and Lamar head to a Vagos gang member's house in Vespucci Beach to repossess a motorcycle. Things go sideways when the owner refuses to cooperate, leading to a shootout and a high-speed bike chase through the city.

Complications

This is the pivotal mission where Franklin meets Michael De Santa. Sent to repossess a car from Michael's son Jimmy, Franklin encounters Michael hiding in the back seat. Michael forces Franklin to drive the car through the dealership window, which leads to Franklin losing his job but gaining a new mentor.

Chop

Franklin and Lamar chase a gang member through a rail yard with the help of Chop, Lamar's Rottweiler. This mission involves platforming elements and using Chop to track the target.

4. Michael's Story Missions

Father/Son

Michael rescues his son Jimmy from a yacht that gets stolen during a supposed "test drive." This action-packed mission involves chasing the yacht on the highway and performing a daring rescue. It deepens the relationship between Michael and Franklin.

Marriage Counseling

After catching his wife Amanda with her tennis coach, Michael chases the coach to a house in the Vinewood Hills and pulls the deck off the hillside with a truck. Unfortunately, the house belongs to the girlfriend of Mexican cartel leader Martin Madrazo, putting Michael in serious debt.

Daddy's Little Girl

Michael tries to bond with his daughter Tracey by going cycling along Vespucci Beach, only to discover she is partying on a yacht with unsavory characters. Michael and Franklin must rescue her using jet skis in a thrilling water chase sequence.

Friend Request

Michael visits Lester Crest, a genius hacker and old associate, at his garment factory. To prove his worth and set up future heists, Michael infiltrates the LifeInvader offices disguised as an IT technician and plants an explosive device in a prototype phone.

5. Trevor's Introduction and Missions

Mr. Philips

Trevor is introduced in spectacular fashion in Sandy Shores, Blaine County. Upon hearing a news report about a heist in Los Santos that matches Michael's style, Trevor realizes his old partner is still alive. In a fit of rage, he confronts the local biker gang, the Lost MC, in a violent encounter that establishes his unpredictable and dangerous personality.

Trevor Philips Industries

Trevor begins establishing his criminal enterprise by confronting the Aztecas gang and cooking methamphetamine at his trailer. This mission introduces Trevor's special ability — a rage mode that deals extra damage while taking reduced damage.

Nervous Ron

Trevor and his anxious associate Ron Jakowski assault a rival operation at the Sandy Shores airfield, involving stealth, sniping, and a dramatic biplane escape. This mission grants Trevor access to the airstrip for future operations.

6. Major Heist Missions

Heists are the centerpiece of GTA V's story. Each heist requires preparation missions and offers the player a choice between two approaches.

The Jewel Store Job

The first major heist targets Vangelico's jewelry store on Portola Drive. You can choose between:

  • Option A – Loud: Storm the store with firearms and intimidation
  • Option B – Smart: Use knockout gas through the ventilation system for a subtle approach

The Smart approach generally yields a higher payout with fewer complications. Preparation involves stealing a pest control van, acquiring gas grenades, and obtaining getaway vehicles. This heist pays off Martin Madrazo's debt.

The Merryweather Heist

Trevor discovers a secret device at the bottom of the ocean guarded by the private military company Merryweather. The two approaches are the Freighter (assaulting a cargo ship) and the Offshore (using a submarine). Regardless of choice, the crew is forced to return the device, making this a heist with no payout.

The Paleto Score

The crew robs a bank in the small town of Paleto Bay to fund the FIB's off-the-books operations. This mission is an homage to the film "Heat," featuring heavy body armor, miniguns, and a prolonged firefight against the military. There is only one approach for this heist.

The Bureau Raid

Michael and the crew must infiltrate the FIB building to steal incriminating evidence. The two options are:

  • Roof Entry: Rappel down from the roof after a helicopter insertion
  • Fire Crew: Disguise as firefighters and enter through the lobby during a staged emergency

7. Mid-Game Story Missions

Three's Company

All three protagonists work together for the first time in this mission. Michael rappels from a helicopter piloted by Trevor to extract an informant from the IAA building, while Franklin provides sniper cover from an adjacent rooftop. This is a landmark mission in the game's narrative.

By the Book

One of the most controversial missions in the game, Trevor interrogates a suspect using various methods to extract information while Michael acts on the intelligence. This mission sparked significant discussion about its content and themes when the game was released.

Hood Safari

Franklin, Lamar, and Trevor visit Grove Street for a drug deal that turns into an ambush. The trio must fight their way through Ballas gang territory and escape via the Los Santos River on jet skis.

Caida Libre

Trevor shoots down Martin Madrazo's cousin's private plane using a rifle, then chases the crashing aircraft on a dirt bike through the desert. This exciting mission leads to the crew obtaining important documents from Madrazo.

8. FIB and Government Missions

The Government Web

Throughout the mid-to-late game, Michael is caught between corrupt FIB agent Steve Haines and IAA operatives. These missions involve sabotaging government operations, stealing sensitive data, and playing both sides against each other. Key missions include:

  • Monkey Business: Infiltrating a government research facility using diving gear
  • Predator: Hunting down O'Neil brothers in the forest using thermal vision
  • Derailed: Assaulting a moving train and transferring cargo to a waiting vehicle
  • Fresh Meat: Rescuing Michael from a Chinese slaughterhouse after he is kidnapped by the Triads

9. The Big Score – Final Heist

The ultimate heist targets the Union Depository, a facility modeled after the Federal Reserve. This is the most elaborate and highest-paying heist in the game.

Approach Options

Option A – Subtle: The crew disguises themselves as security guards and uses modified cars to transport the gold. This approach involves less combat but requires precise execution and timing.

Option B – Obvious: A full-scale assault using military-grade equipment, including drilling through the vault wall and airlifting the gold with helicopters. This approach is more action-heavy but equally rewarding.

Both approaches require extensive preparation, including stealing vehicles, equipment, and getaway cars. The payout for this heist can reach over $200 million when split between the crew, making it the most lucrative mission in the game.

10. Ending Choices and Outcomes

After The Big Score, Franklin is given a critical choice that determines the game's ending:

Option A – Kill Trevor

Franklin and Michael corner Trevor at an oil field. Trevor dies in this ending, and Franklin loses his friendship with him permanently. The remaining characters split Trevor's share of the heist money.

Option B – Kill Michael

Franklin chases Michael to a power plant, where their confrontation ends tragically. Franklin loses his mentor, and the remaining characters share Michael's portion.

Option C – Deathwish (Recommended)

This is widely considered the canon ending. Franklin refuses to betray either friend, and the trio teams up to eliminate all their enemies — including Steve Haines, Devin Weston, Stretch, and Wei Cheng. All three protagonists survive, keep their full heist earnings, and remain friends. This is the most satisfying and complete ending to the story.
