Michael Woods stars as Tony Giordani, a narcotics agent who learns that his wife has been murdered while he is recuperating from an attack by a mysterious stranger. His boss thinks it's a Mafia vendetta, but Tony follows the clues to an empty house which his wife had been photographing on the day of her murder. There, he finds a burned corpse and several clues leading to the Full Moon Killer, who has been decapitating prostitutes around the city. The owner of the house is an insane countess, whose escape from an asylum leads to yet another murder. Before long, Tony and his partner, Lisa, with whom he is engaged in a passionate affair, find themselves targeted for murder unless they can solve the case.

Lewis Collins is back to leading mercenaries on the move in Southeast Asia. This time the cast is unusually good including Lee Van Cleef, Brett Halsey (Cop Game), Romano Puppo (Robowar), Mike Monty (Raiders of Atlantis), Bobby Rhodes (The Great Alligator), etc. Anyway, Van Cleef has Collins go on some random mission to locate a disc with all sorts of valuable crazy intelligence data on it. It just happens that Donald Pleasence, a random government official, hires another mercenary-for-hire Manfred Lehman to tag along and make sure the data ends up in the right hands. Van Cleef isn't taking any chances, and since he is crooked and murders Collins's other bosses quickly, he places Romano Puppo in the group as well to make sure the operation runs smoothly. Collins may not be too expressive but at least he seems to figure out quickly who's out to get him, so the mission continues with lots of double-crosses, twists and turns, and of course lots of explosions!
