Based on Jay Ward's classic cartoon, Mr. Peabody is the world's smartest person who happens to be a dog. He and his "pet" boy Sherman discover that someone has stolen their time traveling WABAC machine and is changing moments in history to disastrous and comical results. It's up to this most unexpected of father-son teams to somehow put a stop to this villain before his actions destroy the space-time continuum in "Mr. Peabody & Sherman."
