Do San (the God of gamblers) is a legendary gambler helped by his supernatural abilities. He undertakes to help a friend pay a debt by beating his friend's advisory at the card table. Despite being assigned a bodyguard, Do San has a freak accident which leaves him with partial memory loss and at a child's mental stage. Small-time hustler Knife, his side-kick, and his girlfriend look after Do San because they were responsible for his accident. After some time they discover that he has not lost all of his powers and take him on a round at the local gambling halls. After being chased by both Knife's loan-shark and enemies closer to Do San's home, a final showdown could take place at the card tables.—Staale A. Olsen
