Early XVII century. A summit between France, England, Portugal and the Pope is to take place in Spain, home of the masked hero known as Red Eagle. The countries are coming together under the guise of looking for a solution to the conflict between Spain and Portugal; however, the ulterior motive is to attack the Kingdom of Spain. The Marchioness of Santillana and her fellow conspirators have hired an assassin to finish off the Red Eagle to guarantee the outcome of their plot. The townspeople and the whole kingdom will be at the mercy of the traitors, but the Red Eagle will be there to help them.
