Francisco García San José

A painter becomes obsessed and begins an affair with a mysterious woman who was touched deeply by one of his works.

Hector Doriani (Paul Naschy) is a stage and screen actor who feels himself living in the shadow of his dead twin brother, Alex Doriani, once a famous star of horror movies. Alex’s young son, Adrian, now lives with Hector in an isolated mansion in the countryside. To keep alive the memory of his father, the boy imagines himself visited by the spirit of the dead man, incarnated in a series of classic horror characters from the past. Eric, Alex’s former butler, now also works for Hector. His main role is to locate and bring to the mansion a series of women who are paid large sums of money by Hector to take part in various sadistic sex games. To complicate matters even further, the games always seem to end with the women getting slaughtered in various gruesome ways by a black gloved, masked killer. Also on hand is horror diva Caroline Munro, as Hector’s housekeeper and cook, who is being pursued by a local priest with whom she once had a much-regretted affair.

After a drug-fueled night of violence, a group of young degenerates and their hostages find themselves stranded in a remote, abandoned church in rural Spain. Their evening of debauchery and blasphemy quickly turns to greed when they discover a local legend that tells of a vast fortune guarded by mummies in the catacombs beneath the ruins. Their lust for the treasure is short-lived as they find that the supernatural horror in the catacombs is something further than fear… it is Beyond Terror!
