Three Vulgarian officers watch a demonstration of their country's new ray gun which can fire other guns remotely. When they hear of the Stooges' escape, they leave the officer's office. The Stooges soon arrive in the office and discover the ray gun, which they think is a new camera. But when Moe and Larry pose in front of the gun, Curly manages to shoot their belts and hats off. The Stooges hide as they hear the officers returning, with Curly taking refuge inside the radio, destroying the wiring in the process. When the officers try to turn on the radio, Curly pulls out a large harmonica and begins playing, while strumming the remaining wires like a harp and banging inside the radio with xylophone mallets. The officers discover Curly, who jumps out of a window to escape. Moe and Larry trap the officers' heads in the window while Curly hits the officers in the head with his mallets.
