The Haunted House of Horror

A group of young adult casual friends in London have convened for a house party. Included in the group are: Sylvia who has just broken up with Bob, her older married boyfriend, although Bob is still pursuing her and she lets him into her life when it suits her needs; Gary, Sylvia's ex-boyfriend with who she would like to get back together; and Dorothy, Gary's current girlfriend. As the party starts to wane, Richard suggests that they move the gathering to an abandoned and purportedly haunted house where he used to play when he was a child, two carloads of them who take him up on the offer. As they partake in activities there associated with a haunted house, one of them ends up being murdered, slashed to death. Chris, the alpha male of the group, takes charge in the aftermath, he advising that they not involve the police but dispose of the body under the circumstances: in the belief that the murderer is one of them, and that they should work out who among them is the perpetrator.
