Bruce Forsyth and Tess Daly host the celebrity ballroom dancing competition. With eight male stars and their professional dance partners having battled it out in a first round waltz or cha-cha-cha, the two couples with the lowest combined judges' score and viewer votes must perform again in a dance-off. Only one team will be saved by the judges, while the other will have to leave the competition. With special performances and behind-the-scenes footage from the first show.
