The film, an English-language Mexican production, was released theatrically in the U.S. in June 1981 to predominantly negative reviews; however, over the years, it has achieved cult movie status.

In the present day, couple Mark and Jennifer Baines explore the temple where they find a small casket containing a severed hand which they take back to their hotel room.

Disturbed by his new left hand, Matson arrests Jennifer under false pretences and heads to a plastic surgery office.

Later, the hand finds and corners Jennifer at her motel and attempts to possess her as well but is saved by Father Cunningham and they both flee to the church.

Father Cunningham leaves and is asked to administer last rites to a car accident victim who no longer has a left hand.

[8] Caitlin Huggins from HorrorNews.net gave the film a negative review, criticizing its plot as 'confusing and hurried', as well as its dumb and unlikable characters.

[11] Dan Budnik from The Bleeding Skull called it "a rather tedious demon possession movie with a great title and lots of killer hands running around".
