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!

A cruel dictator rules a Latin American state. Corruption, brutality and exploitation are present every day. A few people begin to organise resistance. Under the leader "El Leopardo" a small group of guerillas fights against the violent government.
