Rob Brydon joins regular team captains David Mitchell and Lee Mack for the third series of the show about truths and lies. They are joined by guests Carol Vorderman, Larry Lamb, Jo Brand and Russell Howard. In each episode, panellists must read out statements about themselves from a card they've never seen before, some of which are lies and some of which are true. It's up to the other team to cross-question, quiz, and scrutinise each claim with the aim of spotting what's true and what's not. In other rounds, a mystery guest is brought into the studio who has a close connection to one of the guests. Three players will claim it's them that has the connection, it's up to the other team to spot who's actually telling the truth. Plus, Rob Brydon introduces archive footage linked to outrageous celebrity facts which may or may not be true.
