Set during the Mexican Revolution, a man known only as "The Dutchman" (Peter Graves) has a plan for a robbery and brings together four of his old buddies. Each man brings with him a specialized talent: Mesito, a Bluto-like strongman, Captain Augustus, an expert with dynamite, Samurai, a deadly killer with a sword and Luis, an acrobatic fighter.

Each of the men is promised a reward of $1,000 if the plan succeeds. Their mission is to rob a train carrying half a million dollars in gold dust owned by an evil Mexican General and give the gold to the Mexican revolutionaries. Unfortunately, the train is guarded by hundreds of heavily armed soldiers and it must pass through a steady stream of military checkpoints.

A great early Euro-western, one of the first films written and co-directed by Italy's Dario Argento.
