Mr. Peabody is the world’s smartest person, he just happens to be a dog. When his “pet” boy Sherman uses their time travelling machine without permission, moments in history begin to change and things start to spiral out of control. Now it is up to Peabody, with his genius-level IQ, and his pal Sherman to turn things back to normal before the time-space continuum is completely destroyed.
Based on the classic cartoon by Jay Ward.
