Anna has everything to make her happy - a husband, a lovely little house in Bethnal Green, two much-longed-for twin baby boys. But recently her husband Frank has been acting differently. He's started coming home late, drinking more heavily. More than once Anna has been sure she's caught a whiff of perfume on his shirts. When confronted, Frank brushes Anna's cautious questions aside, but somehow, Anna knows deep down that something is wrong in their marriage. Anna's sisters run an upmarket escort agency from a fine Victorian house nearby. It can be a risky business, but watching the carefree, laughter-filled banter of the women who work there, Anna begins to long for the girl she once was. Does being a wife and mother really mean that her dancing days are over? Maybe not. Old family friend Rob, a policeman who walks a fine line between right and wrong, is keen to show Anna a good time, even if her husband isn't.
