Complicated plot centers around nitroglycerin and a lot of karate action. A dangerous load of the chemical lands on a beach, and the islanders claim it as their own. Its owner, Lamas, wants it back and threatens to blow up the island. Tong slips out to Hong Kong and appeals to Palance for
help. Assisted by two karate experts, he overcomes Lamas in a violent conclusion. The film is riddled with cliches and is really little more than a series of action scenes strung together. Palance and Ray do give it their best.
