A desperate mother is ready to do anything to save her seriously ill son. When funds were needed for treatment, Arden Gentry agreed to the monstrous offer of her husband, an obstetrician, to become a surrogate mother for a wealthy infertile couple for a lot of money. But everything turned out to be in vain - the son died. And, having broken up with her hated husband, she began to cling to a saving thought - to see the child she gave birth to from an unknown man. He turned out to be a famous tennis player, whose wife died, and he is raising the boy alone. They met and fell in love. But Arden was unable to reveal her secret in time, and now their happiness is in the hands of a blackmailer.
