After years of growing apart, Harold Lee and Kumar Patel have replaced each other with new friends and are preparing for their respective Yuletide celebrations. But when a mysterious package mistakenly arrives at Kumar's door on Christmas Eve, his attempt to redirect it to Harold's house ends with the "high grade" contents-and Harold's father-in-law's prize Christmas tree-going up in smoke. With his in-laws out of the house for the day, Harold decides to cover his tracks, rather than come clean. Reluctantly embarking on another ill-advised journey with Kumar through New York City, their search for the perfect replacement tree almost blows Christmas Eve sky high.
