Plot

Five years after escaping Los Angeles, Dominic Toretto and his crew, consisting of his girlfriend Letty, Tego Leo, Rico Santos, Cara, and Han Lue, are hijacking fuel tankers in the Dominican Republic. Dom suspects the police are on their trail, and leaves Letty behind to protect her from being caught. Months later, in Panama City, Dom gets a call from his sister Mia who tells him Letty has been murdered. Dom heads to Los Angeles to attend her funeral and finds traces of nitromethane at the crash site. He coerces the local mechanic into giving the name of the buyer, David Park, and is informed that the only car that uses nitromethane in the area is a green 1972 Ford Torino Sport. Meanwhile, reinstated FBI agent Brian O'Conner is trying to track down Mexican drug lord, Arturo Braga, whose identity to the public is unknown; his search also leads him to Park.
