In a country, there lived Antonio. He borrowed money from Shylock.
He signed a bond, which states that, if he fails to return the money, a pound of flesh can be cut from his body.
Similarly, he failed, and Shylock filed a case against him. Bassanio(his friend), thought how to proceed. Bassonio's wife, in the guise of a male lawyer, proceeded in the court.

She asked Shylock to be merciful. But, he demanded a pound of flesh. At last, she said that, " Cut the flesh without shedding any drop of blood".
Then, Shylock accepted the money. Thus, Portia saved Antonio's life with her intelligence.
