When a beautiful woman, Crystal Taylor (Jenna Bodnar) meets a photographer, Drake Van Horn (Patrick Williams) whose works exhibit a strangely macabre brand of eroticism, she doesn't realize the danger in which she will place herself. She poses for him, and upon seeing the photo unwittingly makes a Dorian Gray-type pact where she will remain eternally youthful while the the picture exhibits her true age.
