Teddy, Amy and Charlie plan a trip to Chicago to visit their rich great-aunt Nell, where they are instead mistaken for the Duncan Sisters, a famous hip-hop dance duo and are taken to the dance studio of "Shake It Up, Chicago". Amy pretends that she, Teddy and Charlie are sisters in order to accomplish her dreams of being on TV, but since they do not know how to dance, they enlist the help of dancers CeCe Jones (Bella Thorne) and Rocky Blue (Zendaya). Back at home, Gabe and PJ hold a yard sale in hopes of raising money while cleaning out the attic, but wind up selling a cat cookie jar with $500 in it to Mrs. Dabney; Bob is obsessed with a TV show, Higgins and Zork.
