Martin's comfortable world is upturned by his friend's mid-life crises, beginning with his best friend's suicide, and the secret affair he had with Martin's wife.
The wedding looms and there is an atmosphere of impending mayhem as everyone converges on the country
house hotel for the reception. Humiliatingly, Martin is now a dogsbody at Harry's beck and call, and even has
to take on the job of stand-in when the first choice for best man misses his flight. But he is pleasantly surprised
when his schoolboy crush, the gorgeous Ally, is one of the wedding guests.
