Charlie is really funny… and really fat. She spends her life hating high school, living for her next stand-up comedy class, eating whatever she wants, being the funniest person in the room, and not caring what other people think. The two things she loves most in life are food and comedy. So she sits in front of her TV for hours snacking and studying the comedy classics with George, her best friend. Their relationship is perfect - she helps him write his stand-up material for class, and he remains blissfully unaware that she secretly has the world's biggest crush on him. Life is perfect until Olivia, a new student, joins their comedy class and ruins Charlie's theory that beautiful skinny girls can't be funny. And when Olivia steals both her comedic thunder and George's attention, Charlie takes drastic measures to reclaim both her spot at the top of the comedy food chain and the boy she loves. But at what cost?
