Twin sisters Liv and Maddie reunite when Liv returns home to Wisconsin after starring for four years in a hit musical television show in Hollywood. The Rooney sisters realize their polar opposite personalities put their unbreakable twin bond to the test. While their parents play referee between Liv, a cool, confident, social butterfly who loves to sing, and Maddie, a smart, athletic, high school basketball star who opts for high tops over high heels, brothers Joey and Parker seize the opportunity to capitalize on the chaos and get away with as much as they can.
