The remote house in the woods where “House of Abraham” is set, far from seeing eyes, offers unsuspecting visitors a chance to check-in. Only they never check out.

In this horrific thriller, Abraham (Lukas Hassel) is both host and determined helpmate to eternity.

Natasha Henstridge’s Dee is a visitor with a not-so-hidden agenda. She realizes visitors arrive at Abraham’s thinking they know what their options are.

“Because there are plot twists and turns, it’s very hard to describe Dee,” Henstridge, 50, explained in a Zoom interview. “As far as we know, she’s going into a home that’s sort of a wellness retreat. Only it’s really a place for people who’ve decided to put an end to their life with dignity.

“For Dee, it’s what she wants to do at this point in her life. The idea is that this is a shelter for suicide: It’s people coming together wanting to die with dignity on their own terms.

“This place advertises itself as just that. ‘You come. You decide. We’re here to support you in the decision to end your life.’

“That is where it begins. Then it takes on another life of its own and goes from a psychological thriller into a horror realm.”

That’s when visitors discover Abraham lied: Once you enter, no one goes back home.

Before they arrive, people decided how they want to go — drowning, hanging, a gun are among the options.

Is it the graphic, violent depictions that make this a true horror film?

“It is torture. And then why the people want to end their lives in these particular ways is pretty jarring as well. So yes, some of the horror comes from that certainly, because it’s horrific to watch.”

As for the mood on set, were people joking between takes? Or was it Method where the cast remains anxious?

“Everybody’s so different. That’s such a personal journey. But I’m not the actress that can go from watching somebody in a suicide scene to giggling and telling jokes. I’m not that girl.

“I wish I was. I stay a little more in the vibe that I’m doing. However, Lucas is one of the funniest people I know — and a dear friend. So it’s such a testament to his acting how much he can really freak me out in a scene. Then on the drive home, just laugh it off.”

For Henstridge this is, “A really perfect time for reflecting. I turned 50 last year and I’ve got the 30th anniversary of ‘Species’ this summer.”

That film debut — as Sil, a seductive extraterrestrial-human hybrid — “changed my life. And amazingly, it changed my life within a matter of two weeks when the film came out. The whole trajectory of my life changed in that moment.

“I’m so grateful for the film. And now, 30 years later, people still, like two days ago, come up to me on the street or in stores and talk about ‘Species.’ I think, Wow! What an enduring impression it had on people.”

“House of Abraham” arrives in theaters Friday.
