The Croods have survived their fair share of dangers and disasters, but now they face something that will shake their pack to its core: another family. The Bettermans (emphasis on the "better") - with their elaborate tree house, amazing inventions, and irrigated acres of fresh produce within their idyllic walled-in paradise - are a couple of steps above the Croods on the evolutionary ladder. But when a new threat propels both families on an epic adventure beyond the safety of the wall, they're forced to embrace their differences, draw strength from each other, and forge a future together.
