Liv and Maddie Rooney are identical twins who have been leading different lives for the last few years. Maddie is a high school basketball phenom in Wisconsin who prefers high tops to high heels. Cool, confident social butterfly Liv has been in Hollywood for the past four years starring on a hit TV show. When Liv returns home and the girls share a bedroom, Maddie quickly realizes that it's not easy sharing a small space with a sister who has become accustomed to being in the spotlight, for Liv inserts herself into situations when she thinks Maddie needs help. Despite their antithetical personalities and aspirations -- but with an unbreakable bond -- they are able to accomplish pretty much anything they try.
