Sophie's Revenge (2009)

Dumped by her fiancé just two months before their wedding, comic-strip writer Sophie hatches an elaborate plan to get her Jeff back and punish Joanna, the movie star who seduced him away from her. She finds herself a partner, Gordon, an ex-lover of Joanna's, and the two start on a comic adventure full of laughs and tears, aided by Sophie's two best friends, Lucy and Lily. On the eve of her success, Sophie suddenly realizes that she has been so focused on revenge that she has not heard her own change of heart.
