Su and Jack, a 30-something
millennial couple, decide to disconnect from their internet-dominated lives in
Brooklyn by turning off their phones for a week and staying at a remote cabin owned by their friend Raph. During their stay, Jack notices a fuzzy ball-like object in the den, which Su calls a "
pouffe". While Jack is outside, Su secretly turns on her phone and listens to several strange voicemails from her mother about "giant rats" infesting
New York City, which seem to consume
ethanol. After a night of drinking, while the couple make love in front of a large window, Raph arrives outside the cabin but falls to the ground, revealing a "pouffe" behind him. The couple awaken to find that Jack's
sourdough starter is empty and their bottle of
whiskey has been drained. Su realizes that both contained ethanol and that the "pouffe" may be one of the giant rats her mother spoke of. The couple hide upstairs and turn on their phones, finding they've lost signal but learning from various voicemails and texts that the "pouffes" are aliens which feed on ethanol, and that they have invaded New York, forcing an
emergency evacuation. Preparing to escape back to the city, the couple find that the aliens have drained their car's
gasoline due to its ethanol content. They find a
Land Rover in the barn with a full tank of
diesel fuel, which the aliens ignore because it contains no ethanol. Driving through the woods, they witness another couple being killed by an alien. Recalling the alien's attraction to alcohol, Jack throws a bottle of wine into the woods to lure the alien. The scent of ethanol distracts the alien, which sprays a
pheromone and hovers into the forest, clearing their path. Su and Jack hear a baby crying in the other couple's truck and begrudgingly go back to rescue it. A woman hiding in the back of the truck emerges and holds them at gunpoint before driving off in the Land Rover, leaving the couple and the baby stranded in the woods. When the couple begin hallucinating due to the alien's pheromones, Su injects Jack and herself with two needles of
epinephrine from the truck, but they lose consciousness. They wake to find an alien near the baby, who crawled away while they were unconscious. When the alien shoots its
proboscis at Jacks’ chest, Su grabs a knife and cuts it off, which deflates and kills the alien. They discover that Jack's cell phone, stored in his breast pocket, saved him from the alien attack. While climbing to a lookout point, they investigate a translucent structure growing out of the ground nearby. On discovering that their phones have regained signal, they check for information and call
911. While they are distracted, the structure changes shape to trap them and the baby inside a sound-proof bubble, which gradually ascends beyond the atmosphere, joining many other bubbles also rising into space from all over the Earth. ==Cast==
