Comedy sequel starring Kal Penn and John Cho as the eponymous pot-loving twosome. Having just finished stuffing their faces with White Castle hamburgers, Harold and Kumar decide to fly to Amsterdam so Harold can declare his love to his beautiful neighbour, Maria (Paula Garces). Unfortunately, when the bong that Kumar smuggles onto the flight is mistaken for a bomb, the pair are accused of being terrorists and subsequently dropped off at Guantanamo Bay where they are detained by the deranged Deputy Chief of Homeland Security, Ron Fox (Rob Corddry). The two friends manage to escape and make it back to the United States, hoping to prove their innocence. Unfortunately, several obstacles stand in their way, including the dreaded Ku Klux Klan, a one-eyed, inbred monster, and old friend, Neil Patrick Harris (as himself), who takes the boys on an ill-fated visit to a brothel.
