Nerdy accountant Harold and his irrepressible friend, Kumar, get stoned watching television and find themselves utterly bewitched by a commercial for White Castle. Convinced there must be one nearby, the two set out on a late-night odyssey that takes them deep into New Jersey. Somehow, the boys manage to run afoul of rednecks, cops and even a car-stealing Neil Patrick Harris before getting anywhere near their beloved sliders.

Having satisfied their urge for White Castle, Harold and Kumar jump on a plane to catch up with Harold's love interest, who's headed for the Netherlands. But the pair must change their plans when Kumar is accused of being a terrorist. Rob Corddry also stars in this wild comedy sequel that follows the hapless stoners' misadventures as they try to avoid being captured by the Department of Homeland Security.
