Tom Sanger, 33, has just been made redundant from what he thought was a dream job in a record company marketing department. But before he can leave, Fate intervenes and Tom finds himself trapped in a lift with none other than the consultant who lost him his job. Tom would really love to hate her the trouble is the consultant is female, French, and beautiful. Feisty and strong-willed, Eloise, 27, is uncomfortable being forcibly confined with someone she's had sacked. But Tom's mildly juvenile attitude to their predicament helps her hide the embarrassment under a mask of contempt. Secretly, she's vulnerable, claustrophobic, and a little bit attracted to Tom despite his rough edges. As the temperature in the lift begins to rise in the sweltering summer heat, so do the tempers. Tom and Eloise seesaw between war and truce, but eventually hostilities subside as mutual attraction takes hold. Flash forward five years later. Tom and Eloise meet on London's South Bank for the last time. They've had a four-year relationship which broke up six months ago. Tom says he's meeting her to say goodbye - Eloise is moving back to France and a seemingly perfect new life with a perfect new fiance. Against the backdrop of a crisp Christmas evening, Tom and Eloise amble towards the train station and reminisce about their four years together. But as the pair rake over the remains of their relationship, old memories evoke feelings that both have tried to squash. Subtly they interrogate each other's true motives for this final meeting. Are there still shared feelings? Is Eloise's life as perfect as she makes out? And does Tom have a hidden agenda? If so, he has just 45 minutes to win Eloise back before she gets on her train and is gone forever. Is this new spark strong enough to rekindle the embers of their relationship?
