Peter Rhinehart and Hank Colfax are best friends, but their lives couldn't be more different. Peter is a local pastor who is dedicated to his community. He spends his time visiting the flock, attending meetings, and with the holiday season approaching, preparing for the Christmas service and live nativity. As a bartender, Hank serves a much different customer base at his family-owned tavern, including a handful of lonely regulars and the local biker gang. When Peter scoffs that Hank has it easy compared to him, the two decide to switch jobs until Christmas Eve. To their surprise, the responsibilities of both bartender and pastor are similar, but much more difficult than either of them expected. As Peter and Hank begin to see one another's lives in a new light, and each discovers a new love to cherish, their lives are forever changed.
