Penny (Rebel Wilson) has a smart mind, but unfortunately she is fat and fat, so she repeatedly hits the wall on the road of deception. By chance, she met another colleague named Josephine (Anne Hathaway), Josephine's skin was as white as snow and her hair was as clean as satin. Even Penny, who was of the same sex, couldn't help but look at her twice. After a lot of stalking, Josephine agreed to take Penny as an apprentice. By chance, Penny and Josephine met a handsome man named Thomas (Alex Sharp), who was looking for a partner for his plan. The two women decided to have a game to see who could gain Thomas's trust, but as the plan went deeper step by step, they found that Thomas was not as stupid as he seemed.
