Although statues, monuments and even a Catholic church are dedicated to Daniel O'Connell, little is commonly known about Ireland's preeminent champion of freedom, known as "The Liberator", who rose from the dirt floors of a peasant cottage in Kerry to become the first Catholic elected to Parliament in 300 years.

This captivating biopic unfolds through a potent narrative, intimate filmmaking, and a poignant original score that immerses audiences in Ireland's early 19th-century penal times, when newly-minted Catholic attorney O'Connell refuses to be silenced, "takes all Ireland as his client" and leads a peaceful mass movement of peasants that topples centuries of tyranny and oppression.

Exploring pertinent and current political themes, this historical account meticulously follows O'Connell's unwavering commitment to peace, courage, and faith in God through a landscape of high-stakes trials, intense duels, political divisions, and the grim backdrop of a devastating famine. The Liberator vividly depicts the leader praised by historian Wendell Phillips as "the greatest man your Irish race has given to history" and celebrated by Blessed Pope Pius IX as "the glory of the Christian world."
