The main suspect in the murder of a coed is a prison inmate enrolled in a special program.

Ah-nold, long before his movie stardom, made his TV-acting debut as a champion bodybuilder (which he was at the time) visiting San Francisco for a competition. Something (it's not made clear what) has made him incredibly buff and muscled, but has also left him extremely hypersensitive to criticism and with no control over his anger. When he shows off his poses for a young woman, he becomes enraged and unwittingly chokes her to death. He's taken in by a couple and entered into the bodybuilding contest, but broods when he finishes only second.
