Plot Synopsis

Fairly abject and disturbing psychological exploitation drama from the novel Ask Agamemnon by Jenni Hall. The film charts Martin Potter’s desires for an incestuous bond with his sister that involves “just us”. Their relationship is interwoven around swinging London nights of drugged-out parties, transvestites, homosexuality, blackmail, debauchery and eventually murder.

Julian (Martin Potter) and his twin sister Jacki (Judy Geeson) carry on a bizarre sibling relationship and only reveal their secrets to a stuffed teddy bear named Agamemnon. Newly-arrived in London, while their father is absent, they murder the stern housekeeper and set off for a wild night around London’s Chelsea district. When the pair meets bohemian Clive Landseer (Alexis Kanner) and his girlfriend Denise (Marion Diamond) in a London pub, Clive sets his sights on seducing Jacki but can never get her away from the close attentions of her jealous brother. On the fringe of the party scene are such individuals as art dealer David Curry (Freddie Jones), local shark Rod Barstowe (Mike Pratt) and respected politician James Harrington-Smith (Michael Redgrave).

Eventually Clive persuades Julian to join him one evening on his houseboat and after plying him with drugs the pair spend the night with two transvestites. Clive is deeply in debt to Barstowe, and unbeknown to Julian, Clive has photographed the prior-evenings homosexual orgy and threatens to reveal the pictures unless he is paid four-hundred pounds. Julian soon finds himself unable to escape the dark and discovers his fantasies have becomes his worst nightmares. Afterward he convinces Jacki to help him frighten Clive, but Julian is already on the verge of total insanity.
