Fort Courage endures a Japanese invasion in the form of a fierce Samurai warrior (Mako), who has arrived in town in pursuit of a runaway Japanese girl named Miko (Miko Mayama). In their efforts to protect the girl, the troopers run the risk of seeing their fort reduced to rubble by the warrior's powerful karate chops. As it turns out, the strongest defense against the Samurai's hands is little Miko herself .
