Sugimoto and Asirpa's hunt for the tattooed treasure map has led them to a fishing village on the coast, where a deranged serial killer lies in wait. Lieutenant Tsurumi and his renegade soldiers are also hot on their trail, and if he catches up to them it's guaranteed that there will be hell to pay. Toshizo Hijikata also closes in, while an old friend shows up with a secret about Asirpa that no one wants to believe—but it just might take them closer to the gold than ever before…
