A bunch of cool kids (well reasonably young adults anyway, and mostly not that cool) are having a groovy party which unfortunately is boring them. Chris (Frankie Avalon) leads them to an abandoned house out of town. However, as the kids are getting ready for a seance, Gary (Mark Wynter) is brutally murdered. Chris decides that they need to handle this themselves and so they bury Gary's body and seek to discover who committed the crime.
The viewer will of course suspect Bob (George Sewell) - definitely not a cool kid - who was having an affair with Sylvia (Gina Warwick) and was jealous when he saw Gary kiss her. However, it is soon clear there is something else going on...
The story doesn't really have much going for it being rather formulaic, the characters are mostly awful, the acting indifferent and the less we can say about the direction the better. However, somehow this film works and the slasher horror, though spare, does have an impact. Maybe it is the coolness of the setting in Swinging London, especially the interior furnishings of the various flats. A really enjoyable romp, despite everything.
