'Suitable Flesh' is in theaters and everywhere you rent movies on Oct. 27

Heather Graham is getting under the skin in Suitable Flesh.

Based on H.P. Lovecraft's 1993 short story The Thing on the Doorstep, the upcoming erotic thriller stars Graham, 53, as Elizabeth Derby, as psychiatrist who "becomes obsessed with helping a young patient suffering extreme personality disorder," a synopsis describes.

"But it leads her into dark occult danger as she tries to escape a horrific fate," the synopsis adds.

The trailer for Suitable Flesh, which PEOPLE is exclusively premiering, opens by summarizing Elizabeth's "perfect life," "perfect husband" (Johnathon Schaech) and "perfect career" before delving into her intimate affair with her patient (Judah Lewis).

After a sexual encounter with the younger man, Elizabeth begins to question who he really is, following an out-of-body experience.

"Who are you, really?" she asks him, before scenes show her becoming possessed by an evil entity, wielding a variety of weapons and wreaking havoc on those around her.

"What's going on with you?" Elizabeth's husband asks, to which she replies, "Me? I'm just dandy."

Suitable Flesh, which premiered at the 2023 Tribeca Film Festival in June, is directed by Joe Lynch from a screenplay by Dennis Paoli. It also stars Bruce Davison and Barbara Crampton.

Of the original story the film is adapted from, "I read it and immediately I could visualize it," Crampton, 64, told Entertainment Weekly. "I said, 'I want to work on this; let me see if I can get (Alliance Media Partners) to be as crazy about it as I am.' "

"They read it and they all loved it," she added.

Describing the plot to EW, Crampton described the possession as an "entity [that] has traveled through time taking over different people's bodies."

"There's nothing better than being able to entertain the audience but push them a little bit," added the actress, who is also a producer on the movie.

Crampton also called Suitable Flesh — which EW reported was originally developed by Paoli and late director Stuart Gordon — "a sexy film."

"I don't think Lovecraft is inherently sexy, but Stuart Gordon's movies always were," she told the outlet.
