The Stooges are secret agents working undercover at the home of Professor Sneed (Emil Sitka) and his daughter (Christine McIntyre). Sneed is developing a rocket fuel in secret for the government. Captain Rork (Philip Van Zandt) watches the professor through his front window, with hopes of kidnapping him. Of course, Rork and his henchmen capture the Stooges instead, mistaking Larry for the professor. Trouble brews when the Stooges are required to whip up some the fuel, and then write down the formula. It does not take long for the kidnappers to capture the real Professor Sneed, along with his daughter, and throw them all in jail until the formula is disclosed.
