Bonnie Langford, who plays Mel in Doctor Who, reads this novelization of a 1987 TV adventure featuring the Seventh Doctor. The Doctor and Mel win a place on a Fabulous Fifties intergalactic Coach Tour to Disneyland. Knocked off course by a wayward satellite, the coach party arrives instead at Shangri-La, a remote Welsh holiday camp. The peace and quiet of the countryside are shattered by the arrival of a marauding army, tracking down Delta, the Chimeron Queen, with only one thought in mind: her destruction.
