It follows Lauren (Birch) who, after one too many bad boyfriends, launches a blog promoting "The PIG Theory," which insists that you can enjoy all that romance has to offer, but only for six months. At this "Point of Infidelity and Guilt," you must break up before your mate becomes unfaithful.
When Lauren is introduced to the perfect man, Calvin (Klein), an idea strikes to prove her theory wrong: A competition! Calvin will pick five friends who have been in a relationship for longer than six months, and Lauren will pick the enchantress to be their downfall. If three out of five cheats, Calvin must walk away. But if three out of five resist temptation, Lauren must shut down her blog and open her heart to Calvin.
