After four weeks of auditions, the show goes live and the final nine acts take to the stage for the challenge shows. Every week, each of the dancers is set a challenge that must be tackled with their dance captain to create an unforgettable performance. For the first time, the power is in the hands of the viewers; they vote to decide who stays in the competition. For the three dance captains - Cheryl, Matthew Morrison and Oti Mabuse - the pressure really is on, as they each mentor their three chosen acts through the live challenge shows

Among the contestants this week are best friends Harry and Eleiyah, an 80-year-old ballet dancer and a little girl whose father is losing his sight who wins the hearts of everyone.

"Dad Dancing" will be taken to new heights by one of the acts as the auditions for the dance contest continue. Three superstar dance captains will be watching the dancers every move, but it is the audience who will vote to open the mirror.

It is the last of the auditions - followed by the call-backs, where each of the dance captains must choose three acts to captain through the live challenge shows.
