Six archeology students are spending the summer at an isolated rural compound with their college professor, working on an exciting discovery: an ancient mummy, found in the ruins of a temple.

Little do they realize that the mummy was the servant of the Rain God, and that one of them has the ability to bring it back to life to exact its master's deadly revenge. Trapped inside of the compound with the murderous, unstoppable creature, they must join forces to destroy the monster, or allow it to carry out its plans to annihilate all mankind.
