A miracle drug delivers the overnight weight loss you've always dreamed of. But will it turn you into a walking nightmare? Thinestra stars identical twins Melissa and Michelle Macedo. It’s a sweltering Christmas in LA. Penny—plagued by body dysmorphia and cycles of binge eating—impulsively takes Thinestra, a mysterious Ozempic-like drug. That night, she violently expels masses of fat in a painful and grotesque purge. But her discarded flesh returns…and like the Hyde to Penny’s Jekyll, PENELOPE is born. As her ravenous dopplegänger wreaks bloody havoc, Penny struggles to regain control. Can she overcome her hunger before it's too late?
