In a secluded woodland mansion, a wealthy recluse prepares to receive a visitor, a young artist commissioned to paint the dying man's portrait. Over weeks that pass like years, host and guest will exchange glances, touches and accusations. They will undress not only the artist's naivety but also lay bare the corruption of the mansion's other inhabitants. But as the artist experiences a series of strange and terrifying events, slowly descending into madness, he discovers a horrifying truth. In a desperate bid for redemption, the artist seeks to banish the evil that lurks within-the painting, the house and himself. But will he be strong enough to resist the demon's siren call, or will he succumb to the same fate as those who came before him?
