Being dumped is painful. Being dumped because your ex thinks you're too fat is heartbreaking. Rosie Hayes joins a gym in order to lose weight. Secretly she plans to win back her ex-boyfriend, Phil. Gym owner, Jake Matthias, millionaire and entrepreneur, wants to stay single, but every woman he meets seems to be looking for a Happy Ever After. Jake assigns personal trainer, Samantha, to help Rosie lose the weight and get fit. Samantha, who wants Jake for herself, is disdainful of Rosie, especially when she confesses her desire to win Phil back. Rosie is thrilled when Jake picks her for his special boot camp, held in the grounds of his home in Buckinghamshire. Unbeknownst to Rosie, Samantha has invited herself along too. Rosie asks Jake to be her plus-one at a friend's wedding. An event Phil will also be attending. Will Rosie lose enough weight before the wedding to win back her ex? Does she still want to? Will Jake be able to persuade Rosie that this Phil guy isn't good enough for her? And can he stop himself falling in love with her? And what plans does Samantha have for boot camp?
