Based on the writings of David Chapman and Jimmy Brennan, Withdrawal is about Jimmy, a heroin user in a Dublin psychiatric hospital. His thoughts and observations dominate, his subjective voice-over speculating on the lives of his companions. Jimmy leaves the hospital, returning to the city to reconcile with his loved ones, but his withdrawal leads ultimately to a dead end.

In Victorian England, a master criminal makes elaborate plans to steal a shipment of gold from a moving train.
