Rob Beckett and Romesh Ranganathan join the circus, teaming up with West End and Big Top show Zippo's. They learn how to do acrobatics, contortion and knife throwing ahead of their final Christmas performance at Winter Wonderland.

Rob and Romesh are on a mission to crack the world of musicals and land a role in a blockbuster show in London's West End. With the help of Samantha Barks - who stars as Elsa in Frozen The Musical - she guides the boys with some tips and pulls some strings to sort out an audition for one of the West End's biggest productions - Disney's The Lion King.
