Contestants Carolynne and Craig are joined by EastEnders star Nina Wadia, choirmaster and broadcaster Gareth Malone, comedian and composer Vikki Stone and presenter and 2016 Strictly winner Ore Oduba, all hoping to help solve a range of rhyming rounds. Craig and Carolynne go head to head in a quick-fire animated rhyming round, at the end of which the one with the most points gets first pick of the two celebrity teams, and then it's on to three rounds of hilarity! In Mime the Rhyme, Vikki and Gareth describe a celebrity while Ore and Nadia mime a rhyming action. Then it is on to Rhymewatch, where the teams attempt to identify all the rhyming pairs within a short film starring last week's celebrity guest Anton du Beke as he gives an expert dance lesson. Then it's News at Len, where the teams must guess the rhyming headline in four fictional news stories. The contestant with the most points goes on to play Rhyme Against Time.
