Prehistoric family the Croods live in a particularly dangerous moment in time. Patriarch Grug, his mate, Ugga, teenage daughter Eep, son Thunk and feisty Gran gather food by day and huddle together in a cave at night. When a more evolved caveman named Guy arrives on the scene, Grug is distrustful, but it soon becomes apparent that Guy is correct about the impending destruction of their world.
