Carla Moran (Hershey) is a single mother raising three children: a teenaged boy, Billy (David Labiosa), and two young daughters, Julie (Natasha Ryan of Amityville Horror fame), and Kim (Melanie Gaffin). She has a boyfriend Jerry (Alex Rocco) who apparently works away and is absent for the first half of the film.
Almost as soon as we meet the family, Carla is brutally raped inside her bedroom by someone she cannot see. After the attack she begins screaming, alerting her son, who thoroughly checks out the house but is unable to find the assailant. Carla convinces herself it must have been a dream, but when it happens a second time she and the family bug out and stay the rest of the night with her friend Cindy (Margaret Blye).
What's extra unnerving here is that as an audience we too, witness the attacks. We can see the entity pulling Carla's legs apart, touching her breasts, ambushing her sexually...it's almost too excessive.
She enlists the help of a handful of parapsychologists from the local college, who have dabbled in paranormal activity before but have never seen anything of this nature before.
They begin experiments to see if they can somehow harness the entity, and when Carla's boyfriend resurfaces he is aghast at the lengths she goes to to try and rid herself of the supposed demonic spirit. Naturally, Jerry doesn't believe one word of her story, until he is privy to an especially unsavory attack which unfortunately causes him to end their relationship.
With nothing to lose, Carla agrees to a dangerous experiment and complies with the scientist's request to somehow beckon the entity to come to her in a controlled environment. Dr. Sneiderman shows up and tries to reason with Carla, but she's having none of it. Her life has spiraled so far out of control at this point that she fears for her children's lives as well as her own.
As stated, Hershey's performance is stellar, but also of note is the acting of a young David Labiosa, whose character of Billy is especially good as well. His compassion for his mother is honorable as we see him struggle to be the man of the household and in turn protect his mother from her fears, whether unfounded or not. Ron Silver also has a positive performance here, as a psychiatrist who may be getting a little too close to his unstable patient.
The Entity is vital viewing mostly due to Barbara Hershey's excellent portrayal of a woman losing hope and possibly sanity, but also because no one has yet to make a film on this particular subject matter as honest and direct, yet. It doesn't really hide anything, and it sure the hell doesn't wait to scare the pants off you. It just forces it right down your throat. And that lump you feel there, well..it's fear.
