The Door with Seven Locks

When Lord Selford passes away he is entombed in the Selford family crypt with a fortune in jewels. The crypt will only open if all seven locks are released. Family physician Dr. Manetta (Leslie Banks), a descendant of the Spanish Inquisitors with a penchant for gruesome torture devices, now resides in Selford Manor and plans on collecting all seven keys and the legacy for himself. The spooky old mansion features an underground torture chamber museum.
