Stanley is a bellboy at the Fountainbleau Hotel in Miami Beach. It is there that he performs his duties quietly and without a word to anyone. All that he displays are facial expressions and a comedic slapstick style. And anything that can go wrong – does go wrong when Stanley is involved. Then one day, Jerry Lewis, big star, arrives at the hotel and some of the staff notice the striking resemblance. Stanley continues to do what he was hired to do while star Lewis has more trouble with his entourage than the hotel accommodations.
