Dolly Dearest

A toy manufacturer buys the 'Dolly Dearest' factory in Mexico, where the malevolent spirit of Sanzia, a devil child, has taken refuge in one of the porcelain dolls, and eventually takes control of his daughter.
An American family moves to Mexico to fabricate dolls, but their toy factory happens to be next to a Sanzian grave and the toys come into possession of an old, malicious spirit.
