Jonathan Ross presents the last episode in the series in which Penn & Teller aim to find the brightest up-and-coming illusionists. Each show challenges aspiring magicians to try to fool the duo with their most baffling trick in a bid to win the prize of a lifetime - the chance to perform in Penn & Teller's stage show in Las Vegas. This edition features Laura London - whose trick is as amazing as her outfit, a 15-year-old card trickster with nerves of steel and a mentalist with a mind-reading stomach. Plus Martin Daniels, son of magic legend Paul Daniels, performs his dad's all-time favourite trick. To close the show, Penn & Teller perform the world's first underwater card trick - with a shocking twist.
