The screenplay was drawn from a French novel you purchase before the train starts and make you enjoy a relaxing trip. Having a high degree in psychology, economy or social sciences is not required to understand the plot. It gently pulls the leg of people who feel over-proud of their geographical origin. In addition, you would enjoy splendid Scottish landscapes and be incented to one little glass of the best single malt. Imogene, who has to work in London among what she considers as undergrade people, is sent on a secret assignment back to Scotland. On her way by railway, she is fooled by three men on a fishing trip, who pretend being Scottish when they actually are KGB spies... The plot continues in the pure tradition of popular theater. High spirits to Scotland!
