Fatter (film)

Fatter is a 2019 American fetish thriller film loosely based on Stephen King's novel Thinner.

Billie Halleck (Alexandra Daddario) is a sexy, upper class lawyer living with her wife Heidi (Katie McGrath). Billie recently defended an underworld crime boss named Regina "The Hammer" Ginelli (Aubrey Plaza) in court and is now celebrating her acquittal on a murder charge. A drunken Billie attempts to make out with her client as she is driving. Distracted, she accidentally runs over a Gypsy named Suzanne Lempke. She is acquitted in the subsequent proceedings by her friend Judge Carey Rossington (Gemma Chan). The local police chief Daisy Hopley (Tessa Thompson) also obstructs the case by committing perjury for Billie. Outraged by the injustice, Suzanne's sister, Gina Lempke (Ana de Armas), places a curse on Billie on the steps of the courthouse by touching her face and uttering "Fatter". Soon afterward, Billie begins to gain weight rapidly, despite constant exercise and dieting. Heidi, put off by Billie’s weight gain, starts an affair with Dr. Myka Houston (Alice Eve), a fact of which Billie soon becomes aware. In retaliation, Billie begins her own affair with Regina, who comes out as a fat admirer. The previously fatphopic Billie is dismayed to find she is starting to find her new plump form attractive.

Billie learns that Carey and Daisy have also been cursed; Carey has been inflated with air like a balloon, while Daisy’s stomach grows, filled with beer. Billie tracks down the Gypsy camp and tries to reason with Gina; however, she is further angered and makes the curse on Billie worse. She uses her slingshot to shoot a small enchanted donut directly into Billie's mouth, fattening her more and popping a button. Gina taunts Billie about her fatness. Humiliated and horny, Billie vows revenge against Gina and the other Gypsies.

After Billie grows too fat to do any physical action, Regina attacks the Gypsy camp on her behalf and challenges Gina to a fattening dual. They will both attempt to eat and drink as much as they can, and whichever one gets through without bursting wins. If Gina lives she will pop Billie. If Regina lives, she will be bequeathed Gina's powers. They eat, and grow, their clothes bursting off them, leaving them only in their undergarments. Gina uses Regina's FA proclivities to distract her, flirting with and teasing her. Ultimately, Regina wins as Gina forgets to pace herself and pops. Regina smiles. She's going to have fun with her new gifts.

Some weeks later, Heidi is at a cafe with Myka, celebrating her divorce from Billie. They begin mocking her fatness. Suddenly a banquet's worth of food appears before them, and they find themselves digging in unable to stop. They grow fatter, helpless to cease their public display of ballooning gluttony. As they, and many other women in the shop continue to grow, Billie and Regina watch amused, and aroused from the outside window. They are both much plumper, their own waistlines growing contentedly as they contemplate what they should do next.
