God seems to be playing matchmaker when he encourages Joan to ask a school ruffian to the winter semi formal. Joan's date choice doesn't sit well with her parents, however, especially after Will learns the boy has a juvenile record. Will's also digging up some distressing information about his predecessor as chief of police, who, it turns out, is still cashing a paycheck under another person's name. Meanwhile, Luke looks forward to entering this year's science fair with Grace Polk as his partner.

At Helen's insistence, she and Will take a getaway to a spa, but all does not go well when Will cannot forget about his job. And with the parents away, the kids are up to a little recreation of their own. Kevin and his boss, Rebecca, find it hard to ignore their mutual attraction; Joan, as she is trying to sort out her feelings for Adam, is instructed by God to throw a party while her parents are away; Luke helps Joan pull off a successful party.
