In Manchuria during the 1940's, a karate master named Sazaki and hapkido champion Wang make plans to rob the Korean Independence Army of its funds. However, unknown to them, the money is guarded by one Mr Lee--a grand master of taekwondo.

One Sunday, a penniless unmarried young South Korean couple meet, as they do every Sunday; while the pregnant young woman believes they are not ready to bring a child into the world, the young man decides to go visit his friends to borrow money for delivery.
