La Puerta Negra

A presumed-dead man's current wife and former wives squabble over his funeral arrangements.

Six years ago NASA discovered the possibility of alien life within our solar system. A probe was launched to collect samples, but crashed upon re-entry over Central America. Soon after, new life forms began to appear and half of Mexico was quarantined as an infected zone. Today, the American and Mexican military still struggle to contain "the creatures," while a journalist agrees to escort a shaken tourist through the infected zone in Mexico to the safety of the U.S. border.

When half-breed Indian Yaqui Joe robs an Arizona bank, he is pursued by dogged lawman Lyedecker. Fleeing to Mexico, Joe is imprisoned by General Verdugo, who is waging a war against the Yaqui Indians. When Lyedecker attempts to intervene, he is thrown into prison as well. Working together, the two escape and take refuge in the hills, where Lyedecker meets beautiful Yaqui freedom fighter Sarita and begins to question his allegiances.
