Emma Lloyd (Uma Thurman) is a successful radio-talk-show host who dispenses relationship advice. She advises a distraught caller named Sofia (Justina Machado) to dump her fiancé, Patrick (Jeffrey Dean Morgan), on the eve of their marriage, which Sofia promptly does. To get revenge, Patrick has records altered so it looks like he has gotten married to Emma, which throws a wrench in her plans to wed the man (Colin Firth) she's already engaged to.
