Avalon

Andrew was both surprised and delighted to inherit a house from his aunt, Hilary. After she moved to New York, he hadn't seen or heard from her for years. He moved in with his girlfriend, Rachel, and when two friends came to stay, they discovered the house was haunted. Unknown to Andrew, his aunt had also arranged for Leonard and Sonia to assist him in dealing with the haunting. Unfortunately, Rachel knows Leonard from a past love affair, which complicates both their relationships.
Andrew eventually recalls that Hilary had caused him to forget their time together. As his past begins to resurface, he remembers living there and being part of her occult group. When he understands why she made him forget, he becomes entangled in a deadly encounter in which he and his friends are confronted by Azazel, one of the most powerful of the fallen angels.
