Winning London (2001)

Lord James Browning Senior co-hosts on his grand greater London estate teams of high-school students to the Model U.N. competition, where each 'represents' another country then their own, mostly as in the national selections. Lord James Junior is supposed to win as preparation to succeed his father as real diplomat, but his personal priority shifts to a crush on a member of unorthodox US team, which came just for fun.
