Home Alone
Kate realizes mid-flight that Kevin was left behind, and upon arrival in Paris, the family discovers that all flights for the next two days are booked, and that the phone lines are still down back home in Chicago. Peter and the rest of the family stay in his brother's apartment in Paris, while Kate manages to get a flight back to Scranton, Pennsylvania. She tries to find a flight to Chicago, but all the flights are booked. Kate is overheard by Gus Polinski, the lead member of a traveling polka band, who offers to let her travel with them to Chicago in a moving van.
