"License to Wed" follows newly engaged Ben Murphy (John Krasinski) and his fianc�e, Sadie Jones (Mandy Moore), who has always dreamed of getting married in a traditional wedding at her family church. The problem is St. Augustine's only has one wedding slot available in the next two years, and its charismatic pastor, Reverend Frank (Robin Williams), won't bless Ben and Sadie's union until they pass his patented, foolproof marriage-prep course. Through outrageous classes, outlandish homework assignments and some pious manipulation, Ben and Sadie are about to find out if they really have what it takes to make it to the altar... and live happily ever after.
