In the span of Lauren and Tom's five-year relationship, they've never had a fight. Their sex life is fine. They get along fine. Everything points to marriage, until Lauren suddenly sees a lifetime of "just fine" yawning ahead of her, and it immediately makes her hungry for a better, fuller future. She just has to decide what "better" really means. One moment Lauren resolves to double down on her commitment to Tom, and the next moment she is ready to blow the whole thing up. So, Lauren does what any reasonable person would do - she does not choose. She does both. In a doomed attempt to have everything she wants without giving anything up, Lauren simultaneously starts an affair with her boss, rents a bachelor apartment, and asks Tom to marry her. When they start to plan the wedding, and her no-strings affair gets complicated, Lauren struggles to save what is most important to her before she loses it all.
