License to Wed (2007)

Sadie and Ben are in love, and although Ben suggests getting married in the Caribbean, Sadie has her heart set on a wedding at the family church, St. Augustine's. Ben says sure, and they meet with the pastor, Rev. Frank. The only date open for two years is three weeks away, and Frank insists the kids go through his marriage prep course. They're to write their own vows; he also demands chastity, bugs their apartment, initiates arguments, has them care for robot twins, creates friction between Ben and her family, and raises doubts in Sadie. Desperate, Ben looks for dirt on Frank. Can he undermine Frank's authority and keep Sadie's heart?
