A mockumentary based on the concept that love has an expiration date, 19 Months follows a fictional documentary crew as they trace the relationship of Rob (Benjamin Ratner) and Melanie (Angela Vint), a couple who have agreed to break off their relationship after the eponymous period has passed. Drawn together by the theory that if the relationship is ended before jealousy and boredom set in then the relationship has been a success, Rob and Melanie plan to express all of their passion and emotion for one another in a brief but precious period of time. As the final week of their relationship draws to its mutually agreed upon conclusion and the couple's planned separation draws nearer, this situation gradually becomes more complex than either may have initially anticipated.
