Winning a trip to the Disneyland of 1959, the Doctor (Sylvester McCoy) and Melanie (Bonnie Langford) collide en route with a satellite. The would-be vacationers end up in a Welsh holiday camp called the Shangri-La -- which is presently under siege by the Bannermen, a pair of genocidal assassins who have targeted another vacationer, Chimeron princess Delta (Belinda Mayne). American funnyman Stubby Kaye guest stars as Mr. Weismuller, while British TV game show host Ken Dodd appears briefly as the Tollmaster. Written by Malcolm Kohll, the three-episode "Delta and the Bannermen" began its original BBC run on November 2, 1987. ~ Hal Erickson, Rovi
