There Be Dragons is an epic action-adventure romance set during the turmoil of the Spanish Civil War. The story traces the lives of two young men, Josemaria Escriva (Charlie Cox) and Manolo Torres (Wes Bentley), childhood friends who are separated by the political upheaval of pre-war Spain to find themselves on opposite sides as war erupts. Choosing peace, Josemaria becomes a priest and struggles to spread reconciliation by founding the movement Opus Dei (work of God).
Manolo chooses war and becomes a spy for the fascists. During this time, he becomes obsessed with a beautiful Hungarian revolutionary, Ildiko, who has joined the militia in pursuit of passion and purpose. But when Ildiko rejects him and gives herself to the courageous militia leader Oriol, Manolo's jealousy leads him down a path of betrayal.
He commits heinous acts that will torment him until the end of his life. Only on Manolo's deathbed will Josemaria's message of forgiveness finally have a profound impact on him and on his estranged son, who comes to learn the truth of his father's dark past.
As personal and national battles rage, the characters' lives collide and their deepest struggles are illuminated. Only then can they face the ultimate choices that will result in tragedy or triumph and a chance for final redemption.
