An aristocratic young lady disguises herself as a knight
with the intention of discovering the true nature of the man
she intends to marry. Her disguise fools Lelio, who
confides in her that he loves one woman but is betrothed to
another, a countess. If Lelio refuses to marry the countess,
he must give her a huge sum of money in compensation. Yet he
prefers to marry the other woman, because she is wealthier.
If only the countess could fall in love with another man, his
problem would be solved. The disguised knight agrees to
court the countess not to release Lelio from his marriage
