How do you get over someone who lives under you?
Life for Lucy Jenkins is going OK ... ish. Yes, she's 33, single, and has had to work as a waitress and children's party entertainer since her social worker salary suffered from budget cuts, but she stays positive and manages to pay the mortgage on her flat. Her home is her sanctuary - until Tom moves in downstairs. Lucy and Tom quickly fall in love and into a serious relationship, which is complicated by Tom's recent separation from his wife, who he has two young sons with.
Lucy is heartbroken when Tom breaks up with her, saying that something has to give in his busy life. Encouraged/coerced/badgered by her friends into getting back on that horse, Lucy finds herself at a tacky Singles' Night; dating Danny, a Justin Timberlake impersonator; and attempting a rendezvous with her "special friend." Lucy's quest to move on from Tom would be a whole lot easier if she didn't have to hear everything he does. After all, how on earth do you get over someone when you can hear them peeing?
