Assassinating the nazi general was their mission, but it initiated the resistance.
Honestly, I thought it was some science fiction film. The title sounded like one, so I had to google for its definition. This is an assassination theme, that sets in the early 40s in the Czechoslovakia. The early days of the world war two, where the exile soldiers were sent to eliminate the nazi general Reinhard Heydrich, who was handling the Czechoslovakian affairs. From theirs preparation to the plan execution and the outcome of the result was what this film reveals for us.
