Two Osaka comedians, Makoto (Tomomitsu Yamaguchi) and Kinta (Go Morita), are riding bicycles in Tokyo when they're hit by a dump truck. They regain consciousness in 1945, but not of their own bodies. Somehow, their souls have been transported into the bodies of two tokkotai (special forces, or "kamikaze") pilots.
