Hot Stuff(1956)

The Stooges are secret agents, their mission is to protect Professor Sneed from kidnapping by foreign agents after his rocket fuel formula. They disguise as carpet layers and go to Sneed's house, but Larry is mistaken for Professor Sneed and kidnapped along with Moe and Shemp. They pretend that Larry is Prof. Sneed, and accidentally succeed in making a rocket fuel. But just as they're about to be freed, the real professor shows up and the Stooges are confined to a room, the Professor and his daughter locked in a dungeon, and all sentenced to death.
