Torn between his duty and paternal love, the Venitian doge is forced to exile his son accused of murder. Hopes to prove his innocence run high when his son returns home, but don’t discount their intriguing enemies just yet. I due Foscari sets out in despair and ends tragically. Its music, full of dark hues, awe-inspiring choruses and individual themes for the main characters, already paves the way for Verdi's later scores.
