Based on real events.

Edward Torrens sees something sparkle under the red shoes of a beautiful, Russian woman during a Soviet 'good will' visit to the Rolls Royce factory at Derby, and is forced to investigate alone. But he quickly falls for Yulia, who tells him she has been coerced into stealing the secret materials by Artyom Mikoyan, the 'Mi' half of the MiG aircraft design company.

The Soviets are collecting ten examples of the Nene engine, at that time the most powerful jet engine in the world. Their plan: to steal the secrets of the engine's classified rotor material and copy it.

Edward struggles to foil the Russians while trying to understand his feelings for Yulia, knowing the tragic consequences, if he fails.

Hot love in the Cold War, set against one of the strangest deals the British ever made with Soviet Russia and one that would infuriate the USA.
