Harry has grown up amongst the dregs of society and so it is little wonder that he, like Willi, the estranged father he idolizes, ends up in prison; his young girlfriend Marlies is also incarcerated. Following convictions for car theft, the two are fatefully sent to the same coed penitentiary where Willi and his girlfriend reside. With a little wangling, Harry manages to become his father's new cellmate. Marlies is placed with Willi's girl. The four communicate via toilet pipes as do other inmates. Thus the stage is set for a series of funny and earthy conversations that illuminate and educate both generations of crooks.
