Mr. Peabody (voiced by Ty Burrell) is a business titan, inventor, scientist, Nobel Laureate, gourmand, two-time Olympic medalist, and genius... who also happens to be a dog. Using his most ingenious invention, the WABAC machine, Mr. Peabody and his adopted boy Sherman (Max Charles) hurtle back in time to experience world-changing events first-hand and interact with some of the greatest characters of all time. But when Sherman breaks the rules of time travel, our two heroes find themselves in a race to repair history and save the future, while Mr. Peabody may face his biggest challenge yet - being a parent.
