An epic saga about the secret history of the 1930s American heartland, Damnation centers on the mythic conflict and bloody struggle between big money and the downtrodden, God and greed, charlatans and prophets. The pilot introduces Seth Davenport (Killian Scott), a man masquerading as a small town Iowa preacher in the hopes of starting a full-blown insurrection against the status quo. Focused on his mission, he is unaware that an industrialist tycoon has hired a professional strikebreaker named Creeley Turner (Logan Marshall-Green) to stop the uprising by any means necessary. But unbeknownst to those around them, these two men already share a secret bloody past.
McGowan will play Tennyson Dubois, a charming heir to the vast DuBois industrial dynasty, who is desperate to prove himself as a worthy successor.
