After surviving the end of the only world they've ever known, the Croods now have to find a new place to call home. They set off into uncharted waters, and soon enough, they come upon a walled-in haven that can provide for their every need. Unfortunately, there is one small problem: another family has already taken residence in the area. They are the Bettermans, and they have an intricately-made treehouse, effective farming, and lots of impressive inventions. Needless to say, it doesn't take long for the prehistoric to clash with the modern. Directed by Joel Crawford.
