More Than Sisters (1979)

 

In the tradition of DePalma's Sisters, Twisted Sisters (2006), Mark of Caine (1985), Love Me Twice (1996), Evil Sister 2 (2001), Mirror Images II (1993), and a million other movies about twin sisters, comes this Shaun Costello adult film that holds its own with the best of them.

Martin Randall (Shaun Costello) meets with psychiatrist Dr. Alan Bannister (Jamie Gillis) about his poor wife Alice.

He explains that Alice (Colleen Anderson) was once a sunny girl full of life

They were once a happy romantic couple

But something seemed to change recently when Alice got aggressive in bed.

She was always pretty passive in the sack; suddenly she's barking orders

Martin explains to Alan that things have recently become worse

Alice is haunted by terrible nightmares

The nightmares are so bad she can hardly function

Alice is wheeled into Alan's office; she's a shell of her former self

Alan shoots her up with sodium pentathol to see if she can think back to what's causing this trauma.

In her mind, she sees herself at Harienwood Asylum in Quebec

But her name isn't Alice here, it's Eva - and she acts very differently than Alice

Eva is brash and aggressive 

She hits on her roommate Brenda (Lisa Heyman) 

Brenda pushes Eva away

Eva attacks her

The orderlies break it up... then rape both of them.

Alan takes a break to go see Dr. Miriam Albright (Erica Havens)

Husband and wife lovebirds John (Eric Edwards) and Susie Bollinger (Lynn Stevens) 

Susie receives an interesting call

It's Alan requesting to speak with John.

Alan wants to hire John (a private detective) to find Alice's parents.  Maybe that will be the key to unlocking her mental illness.

John and Susie have sex (softcore only)

Alan shoots Alice up again to reveal more of her past

In this memory, Alice can see Eva being dragged into a room with a bathtub at the sanitarium. 

The memory is so traumatic that Alice screams and struggles to break free

In this memory, Eva is thrown into the tub and raped

 Nurse Oglivie (Lisa Marks)

But there's a happy ending: John is able to uncover Alice's history - and the reveals to Martin and Alice that she had a siamese twin (Eva) that was separated birth.  Alice has been linking telepathically with her long lost twin.  Now that they've found her twin, the issue is resolved and they plan to go meet her.

We get a romantic scene between John and Susie; she states that Martin and Alice are naming their child Susie after her.  What?  I don't really see how she was that impactful - and honestly don't really care about this superfluous couple anyway.

An extremely well made porno with a fairly compelling story.  I suspect the constant "Psycho" sounds were less a nod to Hitchcock than they were a stab at DePalma.
