Fidelio is a two act German opera by Ludwig van Beethoven - his only opera.
"In Fidelio, political prisoner Florestan is unjustly held captive by Don Pizarro, the corrupt governor of a state prison. Florestan's wife, Leonore, searches for him by assuming the disguise of a young man called Fidelio and joining the prison staff as a guard. Her rescue of Florestan offers a universal story of the power of marital love and fidelity triumphing over injustice and tyranny. "
