Synopsis for
The Entity (1981) More at IMDbPro »

In the film, Carla lives with her children in a home in Los Angeles. One evening, she is violently raped by an unseen being, and the molestations and attacks continue. She goes to a local college campus to seek counseling from a therapist (played by Ron Silver) because she suspects she is suffering from some sort of mental illness. He concurs, suggesting that she is manifesting hallucinated experiences based on a fear of sex, possibly instilled in Carla by her upbringing.

However, after another rape, she seeks solace at the home of friends who witnesses paranormal phenomena. Finally assured of the legitimacy of her experiences, Carla seeks help from a paranormal research team. They accompany Carla to her home to try and help, and it seems that they succeed. Unfortunately, when a lover comes to stay the night, he leaves the room briefly only to return and find Carla nude and pinned to the bed by an unseen force. Her breasts are pulsating rhythmically, as if being massaged by unseen hands, while she begs him for help.

Eventually the team of parapsychologists come up with a plan. They set up a home-like location with guns prepared to spray everything with liquid helium. They presume that since the being can manipulate physical things, it must have physical mass, and therefore can be frozen. Unfortunately, the being does strike and is so powerful that it takes control of these spray nozzles and attempts to kill Carla with the helium. Ultimately she faces off with it, (though she can't see it) stating that it can kill her, torture her and rape her but will never touch the core of who she is. In an act of fury, the being bursts the liquid helium tanks and freezes itself, revealing that it is absolutely gigantic in size. All this is witnessed by Carla's psychiatrist, who until now did not believe she was telling the truth.

Ultimately, Carla decides to move out of the house with her family and drives away. The movie ends stating that the attacks, though decreased in frequency and intensity, continue.
