Sean (Stephen Mangan) and Beverly (Tamsin Greig) are a happily married English couple, who are also the successful creators of a hit British TV show. Their life seems complete, that is until a hugely powerful and charismatic US network president persuades them to move to LA to remake their show for American television. He's full of praise and promises "not to change a thing". However, things begin to unravel as soon as Scan and Beverly arrive in LA. They discover that the network president has never even seen their show. To make matters worse, he insists that they replace their brilliant lead actor (Richard Griffiths), an erudite Royal Shakespeare veteran with... Matt LeBlanc! Sean and Beverly are appalled. But the decision is out of their hands. Matt comes on board, and soon Sean and Beverly find themselves in a complicated triangle which threatens to destroy not just their TV show but also their marriage.
