Peter Armstrong and Hank Colfax are best friends, but their lives couldn't be more different. Peter is a pastor who devotes all his time to his church, and Hank has a pub frequented by regulars who avoid churches.
One day before Christmas, Peter and Hank start arguing over whose job is more strenuous, so they decide to switch jobs for the week before Christmas. To their surprise, the duties of a bartender and a pastor are similar, but taking over the other's job is more difficult than they expected. They begin to see each other in a new light and maybe even discover a love that will change their lives forever.
