It's called Paranoid Park for a reason. It's an outlaw skatepark where Streeters rule and Preps enter at their own risk. But when one Prep braves the scene alone, he gets mixed up in a fight that leaves someone dead. In the sleepless nights that follow, he decides to call the police. Then doesn't. He decides to tell his dad. But can't. Desperate and scared, he puts off making any decision. Maybe no one will ever find out. But when a cop appears at his school wanting to question the skaters, the pressure begins to build.
