In the span of Lauren and Tom’s five-year relationship, they’ve never had a fight. Their sex life is fine. Everything is fine. At least it seems that way, until Lauren's parents announce their divorce. Lauren is shaken because she suddenly sees a lifetime of “just fine” yawning ahead of her and Tom, and it immediately makes her hungry for a better, fuller future. One moment she resolves to double down on her commitment to Tom, and the next moment she’s ready to blow the whole thing up. So she does what any reasonable person would do. She doesn’t 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’s most important to her before she loses it all.
