Every dancer needs rhythm, and in the fourth episode of "Step It Up & Dance" we find out who stands out and who falls flat. The contestants are caught off guard with a surprise performance by Luke Cresswell and his crew from "Stomp Out Loud." Cresswell breaks up the remaining 10 dancers into the "call back" team and the "elimination" team. Each group will have to choreograph their own performance that incorporates both "Stomp" and traditional dance moves. One dancer will be declared the winner and another will be sent home.
