ENT doctor Katrin Schwitters meets a charming stranger on a training trip who brazenly introduces himself as a Russian secret agent. Due to a storm, the two are stranded on an island in the North Sea and spend a wondrously playful evening together. Katrin also slips into the role of an agent on a secret mission - "real" life is left out of this exciting flirtation.
