Matt returns from a break at work to the company lunch room, where he meets new employee Melora. A spark ignites almost immediately, but the blossoming friendship is still subject to life's realities of age, responsibility, and commitment. Meanwhile Matt's wife Arianne has plans for a celebratory evening at home that get interrupted by an unintentional spark of her own. Birthday Boy is about what happens when there's a sudden connection between two people that if pursued could interfere with a life that has been going along just fine; about the paths we choose to take and those we choose not to; the commitments we do honor, the worthwhile sacrifices we must make. In short, a celebration of the messy, imperfect, life that being a husband, a wife, a father, a mother, all entails in order to evolve into the grownups we're meant to be.
