American Abby arrives at a hippy commune in England in search of her boyfriend Doug, but the cousin who she has not seen for fifteen years insists that he was never there. Abby nervously reveals that she has a psychic link with Doug and that he sent her a telepathic message, but the commune members ridicule the idea. When they conclude that her boyfriend must still be due to arrive, she asks to stay and is taken in by the eccentric group, one of whom appears to be possibly dangerous. While staying at the cottage, Abby repeatedly hears Doug's disembodied voice calling her name and even imagines seeing him surrounded in flames. Fearing for her lover's safety, Abby becomes convinced that he has met with ill fortune and that a recurring mental image of five elm trees holds the key to his fate.
