Robert Mitchum's son Chris is the star of the Hong Kong-filmed H-Bomb. Mitchum plays a CIA agent who is ordered to locate a terrorist. The villain has stolen a pair of nuclear warheads, and is hiding somewhere in Bangkok. Complicating matters is the fact that the terrorist is the father of Mitchum's onetime girl friend Olivia Hussey. The locations are nice, but the story grinds to a halt halfway through.
