In the chilling vision of director David Cronenberg, a man's desperate search for truth becomes a terrifying descent into biological horror. Art Hindle portrays Frank Carveth, a father fighting for custody of his daughter, who grows increasingly alarmed by the strange physical and psychological symptoms the child exhibits after visiting her mother. His estranged wife, Nola, is undergoing an radical and unorthodox form of psychotherapy at the remote Somafree Institute under the care of the enigmatic Dr. Hal Raglan, played with unsettling intensity by Oliver Reed. As Frank investigates the institute's methods, he uncovers a connection between Nola's emotional trauma and a series of violent, mysterious deaths, leading him to confront a monstrous manifestation of rage and grief. This sci-fi thriller masterfully builds a atmosphere of visceral dread, exploring the terrifying potential of the mind to physically reshape reality, with Samantha Eggar delivering a haunting performance that blurs the line between victim and architect of a terrifying new brood.
