Kill a Dragon

When a valuable shipment of nitroglycerin washes ashore on an island near Hong Kong, the natives think it's theirs, owing to the law of salvage. However, local mob boss Nico Patrai thinks otherwise and gives the islanders three days to return it before he starts killing them. Rather than give in, the islanders hire soldier of fortune Rick Masters to help them smuggle the shipment off the island and sell it in Hong Kong.
