On a stormy sea-shore, fishermen watch a ship foundering in a huge storm. They help the crew come ashore and among the survivors is Gualtiero, who recognises his old tutor Goffredo, now appearing dressed as a hermit. He explains that he has lost everything. Gualtiero tells him that, in spite of his hatred for his persecutor Ernesto, he drew strength from his continuing love for Imogene. (Cavatina: "Nel furor delle tempeste" / "In the fury of the storm / in the slaughter of a pirate's life / that adored image appears in my thoughts"). When the fishermen arrive to inform both men that the noble lady who lives close by is coming to help the shipwrecked men, Gualtiero is urged to hide himself since he will be alone among enemies. He enters Goffredo's hut.
