Northern lorry driver David arrives at a restaurant to meet Celeste with whom he has arranged a date via the Internet. 'Celeste' arrives but is actually called Mia and proceeds to be offensive to him and the waitress. She eventually drops her guard and starts to get on with David but whilst he talks about himself and his late wife, she is enigmatic and leaves without telling him. He catches up with her and they kiss before she flees in a taxi.

Mia is putting herself around town. Stephen is a disenchanted surgeon with a surfeit of self-regard who doesn't know what he is looking for. When Mia gets under his skin, he realises that there might be more to himself than good looks and a high-flying career.

David is trying to put Mia behind him, but meeting Ellie is not the solution he's looking for. She's far too young, honest and insightful, and has some truths to tell he'd rather not hear.

Stephen is waiting for Mia to turn up for a naughty afternoon in a London hotel but soon begins to wonder if he's been stood up.

Mia feels stuck in the difficult position of actually being in a relationship with David. As she is about to meet his children for the first time, events take an awkward turn and she is forced to finally confront the gap in her life which she is attempting to fill.
