Latin American revolutionary Elpidio Acuna sneaks into Hawaii seeking weapons. He and his men break into an armory and steal a large cache of weapons, which they intend to use to further their goals back home. But in the raid, police wound Acuna and capture him. His men escape with him, but he has only hours before the delicate repair to his femoral artery fails fatally. McGarrett wants to find him and the weapons, but even the threat of death won't persuade him. However, McGarrett, and Elpidio's wife Marla, might have something that will.
