Soon after thumbing a ride from a truck driver Johnny McBride is badly burned and suffers from complete amnesia when the vehicle he's riding in blows a tire and goes over an embankment in a fiery blaze. McBride later receives a tip from an acquaintance that a photo of him was placed prominently in the window of a photography studio in a town called Lyncastle so Johnny immediately leaves for the burg in the hopes that something there will jog his memory.
