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? 总主教（哈尔霍布鲁克）指定年轻的麦可神父（班克罗斯）前往新教区驱除在那里作祟的恶魔，在到达圣安格斯教堂后不久，麦可神父便发现自己必须对抗的，是个专门趁人抵挡不住诱惑犯罪时趁机取人性命的女恶魔... 为了解救他的纽奥良教区信众脱离魔鬼的邪恶魔掌，麦可神父必须和这位超级性感的女魔鬼做一场生死对决，他能成功达成任务吗？
