When wealthy couple Richard and Angela visit Marion and Alex in their decaying family home, an evening of drunkenness and sexual rivalry turns bloody as the guests fall victim to an unhinged attacker. Featuring a rare performance from director Bill Douglas (Bill Douglas Trilogy, Comrades), and starring Joanna David and Heather Page (both of whom would go on to work with Douglas in Comrades), this outrageous mix of biting satire and stylish horror recalls the work of otherwise unlikely bedfellows, Lindsay Anderson and Dario Argento. The stellar cast also includes Nickolas Grace, and features cameos by Fulton MacKay, Michael Medwin and Raymond Huntley.
