Dirty Mary, Crazy Larry is a cult 1974 car chase film starring Peter Fonda, Susan George, Adam Roarke, and Vic Morrow. The story deals with two would-be NASCAR hopefuls; the driver, Larry (Peter Fonda), and his mechanic, Deke (Adam Roarke), who successfully execute a supermarket heist to finance their jump into the big-time auto racing world, extorting $150,000 in cash from the supermarket manager (Roddy McDowall in an uncredited role) by holding his wife and daughter hostage.
In making their escape, they are confronted by Larry's one-night stand, Mary (Susan George), who convinces them to take her along for the ride (under the threat of her blowing the whistle on them both). After the heist is reported to the Sheriff, Captain Franklin (Vic Morrow) obsessively sets out to capture the trio in a dragnet, only to find his patrol cars woefully inadequate to catch Larry, Mary and Deke in a high-performance 1969 Dodge Charger. The trio evades several patrol cars, a high-performance police interceptor, and even Captain Franklin himself in a Bell JetRanger helicopter, but finally colliding with a small freight train, in one of the most shocking (and now legendary) movie endings of all time.
