You'll go slap-happy when the stooges go Jap-happy!
The stooges are dressed as Japanese soldiers for their job as magazine models. On their lunch break they go into a restaurant with their Japanese uniforms on causing the proprietor to mistake them for the real thing, and a chase ensues. The boys fall through a trap door, and into a nest of Nazi spies where they are mistaken for 'Naki', 'Saki' and 'Waki', three Japanese saboteurs. The stooges try to act the part, including demonstrating acrobatics and jiu-jitsu to their hosts. When the real 'Naki', 'Saki' and 'Waki' show up, the boys are exposed and impostors, but after a wild fight manage to capture all the Axis spies.
