Parochial school takes a dark and lusty turn for Father Thomas (J. Scott Green), a well-meaning Sunday school teacher who embarks on what he believes will be a quiet summer assignment at a rural academy for girls. It's hard enough for the Father to deal with four sex-hungry students let alone the school's devilish secret.

Six parapsychologists investigate a reputed haunted mansion and are set upon by three flesh-eating succubus ladies under the control of the sinister warlock owner bent on finding a mysterious amulet to give himself more power.
