Prostitutes in burnt out Tokyo ghetto of post-WWII Japan peddle their flesh and save one-third of their money for a proposed dancehall to be named Paradise. The hookers live in a bombed-out building, but they accept the precarious situation with typical resolve.

Intrepid tax investigator Ryoko Itakura sets her sights on the mysterious and philandering Hideki Gondo, a suspected millionaire and proprietor of a thriving chain of seedy hourly hotels, who has for years succeeded at hiding the true extent of his assets from the Japanese authorities. Itakura and Gondo soon find themselves engaged in a complicated, satirical battle of wits.
