The annual Christmas is here again. The family was busy going out to celebrate the Christmas holiday, but they made a mistake and left the youngest member of the family, 8-year-old Kevin (Macaulay Culkin), at home. My parents were extremely anxious, but at this time they were already away and there was nothing they could do for a while. Kevin was very happy. It was rare for him to be alone at home, so Kevin turned his home into a "playground." The two thieves who had just been released from prison looked at Kevin's house. When they sneaked into Kevin's house, Kevin relied on his eye-catching and the "playground mechanism" at home to play a "game" with the two stupid thieves, full of jokes. Can Kevin win this "game" in the end?
