The Irish prisoner is the love story between Luisa Ochoa, a young widow and Conor Doolin, an Irish soldier who was taken prisoner after the English invasion of Buenos Aires in 1806, who became involved with a revolution far away from his roots but closed to the ideal of freedom of his own country. The story takes place at La Carolina, a small charming mining town, embedded in the mountains. Surrounded by an epic atmosphere, the film is an intimate story about love, loss and homeland.
