Beautiful scientist Ilsa Martin has developed a revolutionary method of separating hydrogen and oxygen in water, which could turn out to be the ultimate energy source. A by-product of the discovery is an underwater breathing device capable of supplying its own oxygen and power, and which could be worth $8 Billion; however, a spy ring named Omega then steals the equipment, unaware that it has yet to be perfected.
