The young venetian noble Bassanio seeks to woo the beautiful heiress Portia of Belmont. He turns to his friend, a merchant named Antonio, who agrees to help him financially. They go to a Jewish moneylender, Shylock, who agrees to lend the money - but because of their mutual animosity, Shylock demands 'A pound of flesh' from Antonio as collateral.
Bassanio succeeds in winning Portia's hand. Meanwhile, Antonio's ships are reported lost at sea, and he defaults on the loan. Bassanio rushes back to Venice to help his benefactor where everything comes to a head in Court.
