Intermedio (film)

Intermedio is an American horror film released in March 2005.

They arrive at a longabandoned prospecting settlement which is said to contain miles of underground tunnels, some of which lead to the Mexican border less than a mile away. The four friends climb down into the tunnels, and are observed by a mysterious old man Steve Railsback from a short distance away. He tugs on a mysterious amulet hanging from a chain around his neck and pours what appears to be blood on the ground.In the tunnels, the teenagers stumble into two Mexican drug dealers, Jorge Alejandro Samaniego and Al, along with their teenaged sidekick Zee Paul Cram, hauling packets of contraband across the border. The drug dealers force the four teenagers to tag along with them. Suddenly, mysterious ghostlike creatures appear and begin to attack them, forcing the teenagers and drug runners to join forces and run to the nearest hatch to try to escape. The mysterious old man is seen stroking his necklace, summoning the mysterious creatures. One of them throws a hook and chain at Al, impaling him to the wall. ........
