The new “Harold & Kumar” comedy picks up six years after the duo’s last adventure. After years of growing apart, Harold Lee (John Cho) and Kumar Patel (Kal Penn) 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. Reluctantly embarking on another ill-advised journey with Kumar through New York City, their search for the perfect tree almost blows Christmas Eve sky high.
