Another adventure for the intrepid time traveller. While visiting a Galactic Tollport, the Doctor (Sylvester McCoy) and Mel (Bonnie Langford) win a trip to Disneyland in 1959. On board the spacebus they meet Chimeron queen Delta, whose people have been wiped out by mercenary Gavrok (Don Henderson) and his men. Knocked off course by a satellite, the bus in fact delivers its passengers to the Shangri-La holiday camp in Fifties Wales, but while the Doctor becomes determined to make the most of the break - and Delta embarks on a romance with Earth mechanic Billy - Gavrok is not far behind. Watch out for a guest appearance by Ken Dodd as the Tollmaster.
