San Pedro is a South American country in turmoil, as a new president is about to be inaugurated, but the military don't want this to happen. After some failed assassination attempts, Martin Fierro, an assassin from America is hired to do the job. There's motivation behind this man, as he's convinced that the president was responsible for his father's death. American interests do not want this to happen, so an American dispatch agent (Vaughn) is assigned to eliminate Fierro.
Low-budget b-grade action exploitation with little in the way of attachment and imagination with its scheming and chase elements, but fast pacing and the presence of Robert Vaughn (who looks like he's collecting a simple pay check) makes this junk rather watchable. Vaughn an action star at this time of his career you might be questioning? When he wasn't going about things in a rather effortless manner hiding behind his shades
you gotta say it looks like he was struggling to match the psychical requirements (a lot of running) it was asking from him in certain scenes. However he passed, but it didn't look too easy. Was it dodgy editing? The cat and mouse action set-pieces are far from spectacular (thanks mainly to its minor budget, although the sequence on top of a moving train through a mountainous terrain was when it peaked), but there's dynamic energy and enough going on to keep you glued as two dangerous men (assassin and agent) go at it with knotty political conspiracies being flung about. The choppy plot is somewhat asinine and all over the place with numerous positional poses and a talky script filled political intrigue of very little interest.
