“Prepare yourselves for a new form of extraterrestrial terror,” a new trailer for “Save Yourselves!” announces. The retro spot hints at the “incredible tale of how humans lost Planet Earth” — and furry, cuddly, deadly pouffes are involved.

Written and directed by Eleanor Wilson and Alex H. Fischer, “Save Yourselves!” follows Su (Sunita Mani) and Jack (John Reynolds), a Brooklyn-based couple who are overly dependent on technology. In an effort to unplug and deepen their connection with each other, the pair plan a week-long vacation in an isolated cabin in the woods.

While Su and Jack are off the grid, Earth is under attack by pouffes with “an insatiable thirst for world domination” — and they have no idea. Jack also isn’t quite sure what a pouffe is. “It’s like an ottoman, like a furry footstool,” Su explains.

“It was fairly ambitious to make a sci-fi movie on an indie budget. But that was also what was so exciting to us and made for the most fun parts of the process,” Wilson told us ahead of the film’s premiere at Sundance. “We chose to take a mostly practical approach to the special effects, both because we like the way that fits with the very grounded style of the rest of the movie, and also because it gave us more freedom to play around with ideas without the constraints of budget/per-second bill on every shot.”

The writer-director explained, “There were days where we had to achieve so much tricky puppetry, effects, and camera work — not to mention difficult emotional scenes for the actor — all in one scene. At times, it felt like, ‘Why did we do it this way?’ But it was worth it once we started cutting the footage together and seeing how special it was even before wires had been removed and VFX enhancements had been applied.”

“Save Yourselves!” marks Wilson’s feature directorial debut. Her shorts include “Possum” and “Low Road.”

“GLOW,” “Wine Country,” and “Mr. Robot” are among Mani’s credits.

“Save Yourselves!” hits theaters October 2 and digital October 6.
