As Vince shoots an action movie directed by Nick Cassavetes, he is asked to perform a dangerous driving stunt. Eric and Ari intervene as they do not want him to perform the stunt, but Vince does it anyway; as a result, he crashes the car into the set, but emerges feeling emboldened and invincible. The incident also pushes Vince to seek out new thrills, including sky-diving, purchasing a Harley-Davidson, popping Vicodin pills, and striking a relationship with porn star Sasha Grey.
Vince is then introduced to a new project, Air-Walker, by Eric's associate Scott Lavin (Scott Caan), creating a hostile relationship with Eric; they eventually bury the hatchet and temporarily work together to help further Vince's career. This friendship eventually ends once Eric realises Scott supplied Vince with cocaine at a party. When Vince discovers that Sasha is seriously considering a role in an upcoming porn film, he tries to land her a role in Air-Walker instead. He succeeds, but Sasha sees this as a way for Vince to control her life.
