The Hotel of the AbsentMovie

The young lady-in-waiting of a millionairess is kidnapped, in her stead, by people who had an interest in the disappearance of the rich heiress. The girl is entrusted to a shady figure who has, for years, organized a special "hotel" where - in rigorous segregation - he holds prisoners the people entrusted to him by those who, for reasons of interest, have decreed their disappearance.
