After the thrills and spills of his adventure on "Terror Island", Kip is reluctant to allow Mr Lazarus to send him into another movie - but Beth has other ideas, particularly when she discovers The Paramount Picture Palace is planning to show the latest film in the "Jason Corder" series, "Spy Another Day". Its star, Daniel Crag, has always been Beth's favourite screen actor. When Mr Lazarus asks her to obtain Corder's ID card, she agrees to go in and Kip feels duty-bound to accompany her. But what should have proved a simple visit ends in disaster when Kip and Beth are separated and find themselves in different parts of the same film. Can they find their way through all the dangers of a spy movie and defeat the evil genius, Doctor Leo Kasabian, before the final credits roll and they are trapped there ...forever?
