Anna is recently separated from her husband John, following her affair with a much younger man. The estranged couple accidentally reconvene at the hotel where they spent their honeymoon. And while they try to build bridges, circumstances conspire against them in Britain's most shambolic boutique hotel. Their room is double booked, and a drunken stag party is on the loose. Cue arguments, and a naked best man asleep in their bathroom - which looks very bad for Anna, given her previous form. What happens next will either make or break her marriage for good. Can she manage to avert disaster?

Jed prepares to interview French cineaste and self-appointed expert on the nature of love - Thierry Grimandi. The worldly and somewhat jaded Jed is dead-set on dismissing the auteur's musings as pompous and, well French, until his own relationship with Cheryl starts to fall apart and he is forced to re-evaluate the illusive subject. Soon everyone is talking about love: his relationship counsellor, drinking buddy Marcus and Marcus' girlfriend Sophie Beginnings, endings, tricks...could the French be on to something?
