Fran and the kids prepare to celebrate Christmas alone when Maxwell and C.C. have to go on a business trip.

Mr. Sheffield and C.C. are going to Boston for the weekend, but what originally started as a romantic getaway plan for C.C. turned into family weekend thanks to Niles. Fran, Maggie and Niles have the house to themselves, and Fran decides to throw a singles party at the house to fish an eligible bachelor. But the party is over when an undercovered cop shows up and arrests Fran for not having the required licenses. After spending the night in jail, Fran returns home and Mr. Sheffield almost fires her, if it wasn't for Maggie stepping in and taking the responsibility for the mess. Fran goes to court, but Mr. Sheffield shows up in the last minute to help her from her senile lawyer, Uncle Mannie.

Fran and Niles fight over who gets to ask Mr. Sheffield for the weekend off. Fran wins, and Niles accuses her of seducing Mr. Sheffield to get what she wants. He decides to get back at her and allies with C.C. against Fran. Finally, Niles and Fran forgive each other, and he suggests Fran takes Mr. Sheffield with her to the Fine Family Reunion at the Niagara Falls, the perfect place for him to propose and a solution that will give them both the weekend off. Unfortunately, Fran doesn't listen Mr. Sheffield's proposal. He slips and falls, with no recollection of what happened.
