Action, adventure, and intrigue collide in this impressive drama of a masked hero who fights against injustice in 17th century Spain, and is determined to find out who killed his wife. By day, Gonzalo de Montalvo is a teacher and a father. By night, he is Aguila Roja, or 'The Red Eagle', who fights against the corrupt local sheriff, Hernán Mejías, and Lucrecia, the Marchioness de Santillana. No one knows of his true identity, except for his faithful servant Satur and a mysterious monk. With his ninja-like skills, Gonzalo will stop at nothing to avenge his wife's death, and stop the conspiracies against the Spanish crown.

In season three, the search continues for Gonzalo, as the secret to his past remains elusive. A wedding is in the works for Irene, the cardinal's niece, and Hernán Mejías, but not everything is quite going smoothly as planned.
