The stooges are working as bellboys in a large hotel when a side show promoter shows up with 'Lupe', a wild wolfman who promptly escapes. The stooges try to capture the wolfman by playing music to calm him, but music makes the wolfman go berserk and soon the stooges are the ones trying to run away. The boys end up caught in an elevator with the wolfman who shoots them into the sky.

The stooges are auto mechanics working for the R.A.F. in England. After wrecking an officers car they need a place to hide, but their choice, a sewer pipe, turns out to a bomb which is dropped on the enemy. Finding themselves behind enemy lines, Moe and Curly disguise as German officers and Larry dresses as a seductive fraulein. While general Bommel chases after Larry, Moe and Curly steal the secret plans from the high command.
