The young FBI-agent John Buckner is instructed to bring Huey Walker, a hippy from the sixties, to prison. They travel by train, and of course Huey tries to escape. John looses his freedom and his identity through one of Huey's tricks: He plies him with drink and takes his gun, his hand-cuffs and his passport. Now John gets in jail instead of Huey... When the mistake is discovered John sets off in pursuit Huey.
