Tough Tony Banks (Jackie Gleason) is a malcontented mobster who is perpetually at odds with his wife, Flo (Carol Channing). When Tony receives an unusual assignment from a crime lord known as God (Groucho Marx), he reluctantly accepts and must get himself arrested and incarcerated with the sole purpose of killing an imprisoned convict. Tony's mission gets completely derailed, however, when he accidentally takes acid and has a mind-expanding experience that leads to an ambitious escape plan.
