Fast and furious 4

Five years after the Los Angeles events, Dominic Toretto (Vin Diesel) and his new crew: Leticia "Letty" Ortiz (Michelle Rodriguez), Leo Tego (Tego Calderón), Omar Santos (Don Omar), Cara Mirtha (Mirtha Michelle) and Han Seoul-Oh (Sung Kang), are hijacking fuel tankers in the Dominican Republicdue to his old crew with Leon, Jesse (killed by Johnny Tran), Vince (got wounded and escaped to Rio) and Leticia already disbanded from the first movie. Dominic begins to suspect the trail is too hot and leaves Letty to go elsewhere to avoid being caught. Some time later, In Panama City, Dominic gets a call from his sister, Mia Toretto (Jordana Brewster), who tells him that Letty has been murdered after getting into a near fatal car accident. Dominic heads back to Los Angeles to examine Letty's crash and finds traces of nitromethane. He then goes to the only car mechanic that uses nitromethane and coerces him into giving him the name David Park (Ron Yuan), the man who ordered the fuel.

Meanwhile, F.B.I. agent Brian O'Conner (Paul Walker) is trying to track down a drug dealer named Arturo Braga . His search leads him to David Park. Dominic arrives at Park's apartment first and hangs him out of the window by his ankles before letting go. Brian, who was also on his way to Park's place, saves Park, but Dominic escapes and Park becomes the FBI's new informant. Park gets Brian into a street race through Los Angeles organized by Ramon Campos (John Ortiz) Braga's right hand. The winner will become the last driver on a team that traffics heroin between the United States-Mexico border. Brian selects a Nissan Skyline GT-R R34 modified for better drifts due to RWD using from the Impound Lot. Dominic also shows up to race in his modified 1970 Chevrolet Chevelle. Dominic wins by bumping Brian's car, making him lose control. Brian uses his position as an FBI agent to arrest another driver, Dwight Mueller (Greg Cipes), and takes his place on the team.

The following day, the team meets with Gisele Yashar (Gal Gadot) one of the Braga's men. They drive across the border using underground tunnels to avoid detection, where they meet Fenix Calderon (Laz Alonzo), one of Braga's henchmen. Brian had prior knowledge that after the heroin was delivered, Braga ordered the drivers to be killed. However it was revealed to Dominic from Fenix that he killed Letty and after a tense stand-off, Dominic detonates his car with nitrous to distract Braga's men and Brian hijacks a Hummer with US$60 million worth of heroin. Both Dominic and Brian drive back to Los Angeles and hide the heroin in a police impound lot where Brian picks up a modified Subaru Impreza WRX STI. Later on, Dominic searches Letty's stuff and discovers her phone. He recalls the last number,revealed to be Brian's number and he realises Brian was the last person to contact her and that he placed her for Braga's driver which resulted in him being attacked by Dominic until he learned Brian put Letty undercover for tracking down Braga so she could clear Dominic's name. Brian tells his superiors that in exchange for Dominic's pardon, he will lure Braga into a trap, forcing him to personally show up to exchange money for the heroin. At the drop site, however, is revealed that the man who claims to be Braga (Robert Miano) is a decoy and Campos is the real Braga, who escapes and flees to Mexico.
