4 friends get caught out while they were street racing, to save them from going to jail they have to help the police take down a well known drug cartel in Rio.
A group of ten illegal street racers own the streets that they drive on, revered by the cops for their uncanny ability to escape arrest by any means possible, including taking out their units. When two sisters enter the scene, it's up to them to take back the roads and destroy who they call "The Street Kings".
