Three robbers escape with loot from a heist, but during the escape, two of them are killed by the other one. Their dead bodies wash up on the shore after a maritime disaster, but a policeman, Yumisaka (Junzaburo Ban), becomes suspicious because they are not listed as passengers. The surviving robber Inukai (Rentaro Mikuni) is sheltered by a prostitute, Yae (Sachiko Hidari). In return, the robber gives her a large sum of money, and she is able to start a new life. The policeman follows Yae to Tokyo on the trail of the robber, but she refuses to cooperate with him.
