Teenaged siblings Girly and Sonny lure young men back to their home to meet the eccentric Mumsy and Nanny. There, the men are forced to take part in strange games, the rules of which are never defined - and if they refuse, or transgress the unwritten rules, they're killed. But they may have met their match in New Friend, their latest victim, who starts to manipulate the foursome, setting one against the other感性的人来拍电影写剧本就是这样，对情绪的感知力让他们能够准确、快速地捕捉到人们生活的喜怒哀乐，并加倍地呈现出来，堆叠直到高潮。 Bizarre combination of late sixties avant garde and sleaze. Director Freddie Francis had made horrors for both Hammer and Amicus but this is nothing like any of them. Shot on location with an atmosphere mixing playground horror and conservatory theatre that is downright weird and unsettling. The great lost girl of sixties British horror, Vanessa Howard, shines as she does in those other rarely seen gems Corruption [1967] and What Became of Jack and Jill [1972]. If Harold Pinter had made The Texas Chain Saw Massacre [1974] for the BBC this could have resulted. Excellent and unique.
