Clark and Audrey chase after Ellen, who has been kidnapped by the Travelers check thief. Along the way, they run into (literally) Rusty having gelato with a California girl (Moon Unit Zappa) he just met, and Clark takes them along. When his car gets a flat tire, Clark steals a bicycle and continues to follow Ellen, leaving the kids behind to tend to the man in the trunk. When Clark catches up to the car, a red Volkwagon convertible, Ellen pulls him off the bike and into the car. In the chaos that ensues, the thief drives the car into a Roman fountain. The police arrive and capture the thief, Ellen embraces Clark for being her hero, Rusty admits to his new friend that his parents are pretty cool, and Audrey just asks if they can go home now. The next day, as their Pan Am jet approaches New York, Clark and Ellen profess their delight at being home again. In the final scene, Clark mistakes the door into the cockpit as the lavatory door and stumbles on top of the pilots, causing the plane to go into a nosedive that knocks the torch out of the hand of the Statue of Liberty. Yup, the Griswolds are back.
