Meet Jim Carrey. Sure, he's an insanely successful and beloved movie star drowning in wealth and privilege—but he's also lonely. Maybe past his prime. Maybe even... getting fat? He's tried diets, gurus, and cuddling with his military-grade Israeli guard dogs, but nothing seems to lift the cloud of emptiness and ennui. Even the sage advice of his best friend, actor and dinosaur skull collector Nicolas Cage, isn't enough to pull Carrey out of his slump.

But then Jim meets Georgie: ruthless ingenue, love of his life. And with the help of auteur screenwriter Charlie Kaufman, he has a role to play in a boundary-pushing new picture that may help him uncover a whole new side to himself—finally, his Oscar vehicle! Things are looking up!

But the universe has other plans.
