Osamu must find the kidnapped son of a magnate. The son was known to consort with a cabaret singer, so Osamu goes to investigate her first...

Akira and Osamu wake up to discover a baby left on their doorstep. They have no means to take care of it, so they entrust it to a local doctor, who wants to adopt it, and hires them to find its parents (to draw up real adoption papers).

Osamu and Akira have to kidnap a disabled bride away from a forced marriage.
