The film is adapted from a true story in the United States in the 1940s. Fernandez (Jared Leto Jared Leto) is a professional swindler who uses his usual means to get to know nurse Baker (Salma Hayek Salma Hayek) through the Lonely Heart Friends Club in an attempt to defraud her of her money. However, Baker, a poor man on the dole, found that Fernandez, who was unprofitable, decided to end the relationship with Baker. Unexpectedly, Baker was so deeply in love with the liar that she was even willing to stay with him and cheat with him. Fernandez used his good tricks to win the favor of all kinds of women, and the real and fake games between them made Baker's jealousy and possessiveness infinitely inflated. She often kills deceived women with complex psychology, and more than 10 innocent people have died at their hands-including a woman who has given birth to Fernandez's child. This pair of lovebirds, which are talking about blood, have attracted urgent investigation by the police, and the law net of restoration is right in front of us.
