Vamos a matar, compañeros

Yodlaf Peterson (Franco Nero) is a suave Swedish arms dealer with a love for fast money. Vasco (Tomas Milian) is a trigger-happy Mexican bandit with a hate for suave Swedish arms dealers. But when the two team up to kidnap a professor who holds the key to a fortune in gold, they find themselves hunted by the American army, stalked by a marijuana-crazed sadist (Jack Palance) and trapped in the middle of a revolution about to explode. Can these two enemies blast their way across Mexico together without killing each other first? (texto oficial do distribuidor)
