 In New Orleans, a series of horrific murders of priests are occurring around the city s Catholic churches. The diocese calls in Father Michael (Cross) to fight the powerful demon, known as Daesidarius, or The Unholy. The Father s faith is tested almost to the breaking point as the demon - disguised as a stunningly beautiful lady - attempts to seduce Father Michael into breaking his vows. Father Michael soon learns how the Unholy works - by murdering the sinner in the act of sinning, then sending that person s soul to Hell. Will this one priest s inner strength be enough to stop this monster - or will he join the ranks of the other ill-fated priests?
