When Tom and Ellen are together, things seem to work. It's only in the spaces outside the relationship - the intrusions of real life, and the deadly collaboration of parents, siblings, friends and exes - that the flailing attempts to make good first impressions, arrange first dates and hold a relationship together, seem to unravel.
An episode of Sharpe inspires Tom to invite Ellen to the most romantic spot in the UK. His parents, sister, Ellen's flatmate and ex all decide to come too.
It's the hottest day of the year and everyone's on heat or in uniform.
