In this stock, low-budget occult horror film, a tiny 2-inch-high Aztecan idol is stolen from a professor and ends up in the experimental hands of three high-school students who use it in some creative attempts to get in touch with the spirit world. Things start to go wrong when a cemetery worker dies during one of these spirit sessions, and everything goes wrong after the Aztecan god possesses the body of a young man who steals the idol for his own purposes. Special effects create the appropriate flying objects and body bulges where needed, and makeup is grotesque enough by anyone's standards, but these pluses cannot erase the lack of interesting characters or situations or the uninspired acting.
