Meet Molly Bennett. She's just passed a 'landmark birthday' and is mother to two hormone-driven, warring teenagers. She's married to Max, who buys her last-minute birthday presents in M&S, and works for a man prone to snooping through her emails. Maybe she needs some more excitement in her life. Everyone seems to be having a better time of it than her, especially her Dad who's in Thailand searching for a new wife, and her next door neighbour Ellen with her string of toyboys. So when Max starts taking an increased interest in keeping fit and going on 'business trips' abroad and less of an interest in their sex life, Molly begins to despair. That is until an old school friend starts flirting with her through Facebook. What will happen if Molly does something out of character and stops being the person everyone wants her to be?
