Deliveryman "Mad" Max Grabelski (Daniel Stern) is charged with delivering packages to millionaire Reinhart Bragdon (Anthony Heald) for $50 tips. During a late night delivery, Max accidentally stumbles across a fire in Bragdon's mansion and is cornered by FBI Agent Palmer (Jon Polito), but accidentally picks up Agent Palmer's gun and manages to escape. Max later sees a news report in which Palmer claims that Bragdon was killed in the fire, which was set up by Max to stop him from exposing a money-laundering conspiracy. Now on the run from the law, Max contacts his boss and learns that a final package is to be delivered to Bragdon, but at his mountain cabin in Devil's Peak.
