Set in the 70s on the US/Canadian border three teenage boys grow up quickly in a dangerous situation. Mort, Tim and Danny frequently drive across the border bridge to go drinking and visit strip joints in Canada. One day they meet a hippie who persuades them to smuggle a tyre-load of marijuana. However when they arrive to do the job the dealers turn out to be pretty nasty and pull out guns forcing the boys to take heroin instead. As they approach the border post the boys are faced with a decision which could affect the rest of their lives.
