This is an atmospheric sex-horror, akin to "Jesus Christ: Serial Rapist." 

   A perverted landlord rents a house to a schizophrenic.  The schizophrenic is pre-occupied with religious images.  The landlord decides to go on a rape spree, making sure to alter the crime scenes in ways that will incriminate the mentally ill tenant.  Will the vile rampage go unchecked?
