Round 1
Cat Deeley hosts the dance competition, as the contestants perform in couples for the first time, in the knowledge that two of them will leave the contest by the end of the night.
So You Think You Can Dance continues, as Cat Deeley and judges Nigel Lythgoe, Arlene Phillips, Louise Redknapp and Sisco Gomez lead the search to find Britain's favourite dancer.
Training with world-class choreographers and working across an array of dance genres - lyrical hip-hop to disco, commercial to jazz, or broadway to ballroom - the top 20 dancers take to the floor hoping to impress the judges and win valuable viewers' votes.
Performing in couples for the first time, who will make a good first impression, and who will be forced to dance for their lives and their place in the competition? The pressure is on, and in the result show one boy and one girl will take their final bow and dance their way out of the contest, and out of the running for the chance to dance in Hollywood and take home the 50,000 pound prize.
