Eddie Marquez is an infamous criminal looking to start a new life with his girlfriend, hoping the Western sun will scorch away the sins of his past. He has one last drug deal to make before he can put it all behind him. But four disgruntled cops refuse to let him walk free, setting out to take the law into their own hands.

They will plunge into a long-forgotten labyrinth of caves, deep into the earth, searching for salvation from the menacing predator outside…and the horror hiding within.
