Aspiring actor Sam and his botanist girlfriend Rylie have travelled to rural New England to investigate an outbreak of an ergot-type fungus called "sordico" that has been devastating local farms. They camp on a remote farm after their car breaks down, but elderly farmer Eulis, claiming to be the landowner, asks the couple to leave. Sam and Rylie return to their car to discover its battery died, leaving them stranded. They look for help at a nearby farmhouse and meet Karen, an eccentric old woman, and her supposed son Gunni, who is mute, partially catatonic, constantly watching vintage cartoons, and wears bandages around his head. Karen explains Gunni's bizarre behavior by claiming a bull kicked him in the head.Karen supposedly calls a mechanic named Pete to come and jumpstart the couple's car. While waiting, she feeds Sam and Rylie strange food that conflicts with their strict vegan diet, while also engaging in odd conversation, which includes Rylie asking about weird Polaroids of Karen's family. When Pete fails to show up, Karen sets up Sam and Rylie with sleeping arrangements in the cellar. Addicted after years of maintaining his diet, Sam leaves Rylie alone to gorge on more of Karen's food in the kitchen, and Gunni experiences a seizure while seemingly trying to say something to Sam. Sam then passes out and has a dream where everyone turns into Popeye characters discussing a medical condition with his stomach. Meanwhile, Rylie investigates unsettling sounds in the cellar. Sam returns to the basement to find her missing, and he also discovers Karen is gone from her bedroom. Sam calls 911 before investigating Karen's barn. However, once he is inside, Karen injects Sam with a drug that knocks him unconscious.Sam and Rylie recover to find themselves restrained on a raised platform and wearing breathing masks connected to gas tanks, one of Sam's buttocks bleeding and bandaged. Karen, Eulis, and Gunni eat at a picnic table beneath the couple. Driven mad from sordico and justifying their lifestyle through a misinterpretation of God's will, Karen explains that she and Eulis became cannibals to compensate for crops turning bad. Karen additionally reveals that she and Eulis "adopt" unwilling participants to feed on. Gunni is revealed to have been a random hunter who was lobotomized before Karen and Eulis began cutting off body parts like his cheeks to eat. Karen and Eulis open a crate containing Delilah, a lobotomized woman without limbs whom they call their daughter. Karen and Eulis feed Delilah pieces of Sam's cooked rump flesh.Eulis prepares to lobotomize Sam when a cop unexpectedly interrupts. While Karen and Eulis deal with the police officer, Sam talks Gunni into freeing him and Rylie. After the cop leaves, Karen and Eulis catch Sam, Rylie, and Gunni trying to escape. Gunni dies after triggering an animal trap. Karen recaptures Sam and Rylie. Some time later, Rylie is seen in Gunni's seat at Karen's table. Rylie is lobotomized, wearing head bandages from having her cheeks eaten, and is visibly pregnant too. In the basement, Sam is seen having been turned into a semi-sentient torso like Delilah. After feeding them, Karen forces Sam and Delilah to have sex. (thanks to Wikipedia)
