Another Christmas is coming. Kevin (Macaulay Culkin), who was forgotten at home and did not go on a Christmas trip in the last episode, is going to Florida with his family to enjoy their Christmas vacation this year. Careless parents will certainly not forget to bring Kevin this time, but their forgetful character has not changed. Seeing that the plane is about to take off, the family rushed to the airport. This time Kevin was not forgotten at home, but was forgotten at the airport during registration, and boarded the flight to New York by mistake! The first time he came to this completely unfamiliar big city, the smart and mischievous Kevin couldn't help but be secretly afraid. To make matters worse, he actually met the two stupid thieves who were beaten badly by him in his home in the last episode. The two had just escaped from prison and ran into Kevin, and this time they naturally wanted to avenge their previous shame. So, Kevin's battlefield moved from his home in the last episode to the Central Park Hotel and Toys "R" Us in New York!
