The Introduction is a roughly 20 minute video, created with Grand Theft Auto: San Andreas' video engine, that details how events in Grand Theft Auto: Vice City led to events in GTA San Andreas. It was available with the American PS2 Special Edition of GTA San Andreas or the official soundtrack double CD. It is set in 1992, and replaces the need for a GTA San Andreas Stories prequel, like Grand Theft Auto: Liberty City Stories and Grand Theft Auto: Vice City Stories (each explained the events leading up to Grand Theft Auto III and GTA Vice City respectively). The video ends directly at the beginning of GTA San Andreas, when Carl arrives in San Andreas after hearing the news about his mother's death.
Frank Tenpenny and Eddie PulaskiThe video features a scene in Los Santos that depicts Frank Tenpenny and Eddie Pulaski, who had just came from a meeting with Big Smoke, and begin discussing Jimmy Hernandez's assignment with them, and the threat from their Partner Ralph Pendelbury. In a later scene, Tenpenny is overheard verbally harassing an unknown person on the phone. When they go to pick up Hernandez, he appears to be a good, straight cop who once struggled in a domestic despute with a guy that beat up his wife and a drug addict mother. Tenpenny is particularly hard on him, saying that it is about a game of percentages and "Screw as many bad guys as we can." Tenpenny then orders Hernandez out of the car. In the last scene featuring the C.R.A.S.H. trio, Pulaski is kicking a downed officer, obviously Pendelbury. Tenpenny hands a pistol to Hernandez, who at first refuses to kill the cop. Tenpenny reminds him of what they talked about and tells him, "You cap him or I cap you." Hernandez reluctantly shoots and kills the downed officer.
Mike Toreno and T-Bone Mendez
Another scene features T-Bone Mendez and Mike Toreno (who is sitting on a parked ZR-350) in San Fierro. Mendez is brutally beating a snitch to death against a shipping container for ratting. After Jose's death, Toreno apparently scolds T-Bone for killing him, however after a call on his cell phone, Toreno then discusses with Mendez about a "buyer down in Los Santos."
Ken Rosenberg and Salvatore LeoneA later thread of scenes documents Ken Rosenberg's path from Vice City to San Andreas after his completion of drug rehab. The first scene depicts Johnny Sindacco in Salvatore’s Gentlemens Club in Liberty City proposing to Salvatore Leone a three-way split between the Sindacco Family, the Leone Family, and the Forelli Family for a new casino in Las Venturas, with Salvatore's five million dollar investment managed by the Sindaccos. Salvatore isn't pleased with the terms of this offer, and names his own terms; he gets control of the books. He then suggests to Johnny that he would be pleased with a "neutral" third-party to manage things, and tells Johnny to get rid of their guy to prove the value of his involvement.
The next scene shows Ken Rosenberg walking out of the Fort Carson Medical Center in Bone County, talking to himself about being sober, being disbarred from practicing law, needing a job, and needing a ride. Later, Ken tries to call Tommy Vercetti from a pay phone, and reveals that he is avoiding Ken's calls.
The following scene in the desert depicts two anonymous Sindacco Family thugs digging a hole for the body of Mickey and burying it, while discussing the rumor that the Leone family is lending their bosses some money. The next scene shows Johnny walking into Salvatore's office to tell him they've gotten rid of their guy. Salvatore suggests a lawyer he's heard about that just got out of rehab; he used to work for the Forellis in Florida.
The final scene in this thread depicts Salvatore barging into Rosenberg's office in Las Venturas, demanding to know why Ken hasn't worked harder to earn his investment back. Salvatore implies that he got this job for Ken so that he could be his man.
Kent Paul and Maccer
Another scene features Kent Paul and Maccer in a recording studio in Salford, England. Their conversation consists of Kent becoming owner of a band, the Gurning Chimps, buying Maccer out of his contract, and Maccer's excitement over going to America.
CJ and SweetThe main thread of scenes in the video, focusing on CJ and the members of gangs in Los Santos, begins with three Ballas members (the sworn enemies of the Grove Street Families) smoking a joint in an alley, talking trash about Grove Street Families, and discussing their plan to murder Sweet.
The next scene shows Big Smoke and Ryder in Ryder's House, having a conversation about "destiny" and "choices" with Smoke convincing Ryder to join him and the Ballas. The scene that follows features Sweet, Big Smoke, OG Loc, and some other Grove Street Members shooting craps on Grove Street. Smoke is warning Sweet that "standing by our principles" may be the reason they're "losing the streets" and becoming soft. Jeffery explains that he's a "Gangsta Rapper", and gives himself the name OG Loc. Smoke and Sweet tell him he should avoid a life like theirs and go to college, "Make something of yourself". Smoke asks Sweet if he's heard from his brother CJ, and Sweet explains that they're not speaking.
The following scene shows CJ in Liberty City, attempting to steal cars parked on the side of the road until he pulls a man out of his stopped Washington and steals it. He then speaks on the phone to Joey Leone, and asks where to take the car, as he needs to get it off the street. There is a quick cut-scene of a green Sabre pulling out of a garage, then the next scene depicts CJ with a pistol mugging a man in an alley.There is another shot of a green Sabre cruising down a road in Ganton, then the final scene features the Sabre driving down the street Sweet's house is on, and then gunfire coming from the car, riddling the Johnson house with bullets, unknowingly killing Beverly Johnson. As the car drives away, Sweet rushes into the house, then back out to stop Kendl Johnson, who was just about to enter. As Kendl weeps on the steps of the porch, Sweet calls CJ to tell him that his mother is dead.
The first mission of Grand Theft Auto: San Andreas continues the storyline from this point on.
- Mickey - Killed by a member of Sindacco Family to get investments for Caligula's Casino.
- Ralph Pendelbury - Killed by Jimmy Hernandez in order to gain acceptance in the C.R.A.S.H. unit.
- Beverly Johnson - Killed by members of the Ballas gang in attempt to kill Sweet.
- Unknown Person - killed by T-Bone Mendez, possibly for snitching
- Almost all the scenes were shot in Grand Theft Auto: San Andreas locations despite the fact they are meant to be somewhere else. For example, Kent Paul's studio in England is actually the interior of Madd Dogg's mansion, and the final scene should take place in Liberty City but is obviously shot in Los Santos.
- One of the possible reasons Tommy Vercetti does not talk in this movie is that Ray Liotta, the voice actor of Tommy, had a dispute with Rockstar North about how much "effort" he put in to Vice City.
- The appearance of Sex Club 7 in the Liberty City scene is a canonical error. Before 1998, it was called Paulie's Revue Bar. This happened because Rockstar wrote GTA: Liberty City Stories after GTA: San Andreas.
- In the Mike Toreno scene T-Bone is seen beating up someone. The person although bleeding heavily appears to look like Jose from the mission Cesar Vialpando who questioned about CJ being in Azteca territory. The white V-neck shirt (although covered in blood) gives off a possible hint.
- Sonny Forelli is mentioned by Salvatore Leone when he berates Johnny Sindacco: "Ever since Sonny Forelli got himself pasted all over Florida you think you run things in this town."
- The drive-by scene is inspired by the final sceneof the movie Menace II Society.
