A recently released ex-convict sets out to collect the gold and jewels he stashed away before being sent up the river in this south of the border thriller starring Mario Almada and Roberto "Flaco" Guzman. They call him La Sombra del Negro, the dark figure who no one wants to cross. When La Sambra del Negro comes searching for the riches he stole in a high stakes robbery, he quickly discovers that his old friend Daniel had invested the substantial take with five other partners. While La Sambra del Negro has few problems ferreting out the first four partners, it's the fifth partner - the big boss - who proves something of a nuisance for the vengeful criminal mastermind.
