Josh and Nat tie the knot just seven months after they began dating. Nat's sister Naomi sums up the thoughts of the happy couple's family and friends when she whispers the film's title to her husband during the ceremony. And, indeed, Nat and Josh soon visit a relationship counsellor, though perhaps they should have picked someone other than Linda, who openly loathes her own husband. And then there's Josh's old flame Chloe, who's still on the scene, and Guy, a handsome client of Nat's, to whom she has clearly taken a shine... do they really stand a chance of making it to their anniversary?
