Plot
Johnny Paul is a flashy gambler and ladies' man living on O'ahu, Hawai'i. In reality, he is agent "Diamond Head" working for a secret US government agency. His mission: stop the theft of a lethal new gas, which has the potential to cause instant death upon contact. The substance was secretly developed by a top battalion of Marines at the request of a Pentagon official named Colonel Millard Butler. However, a double agent had infiltrated the unit, killed Colonel Butler, and assumed his identity. Paul uses his public persona to get close to the double agent, who is known by the pseudonym "Tree". However, once his cover is blown, it's a race against time to stop Tree from selling the secrets to an unnamed foreign power.
