Top obstetrician and gynecologist Su Qingyan spent five years developing a leukemia vaccine to save her husband, only to be betrayed by him—Lu Tingzhou—through infidelity and domestic abuse, and incited by his superstitious mother and the fraudster Mr. Jia into blindly trusting umbilical cord blood folk remedies. After her vaccine was destroyed and her hard work went down the drain, Su Qingyan resolutely divorced him, joined forces with righteous forces to expose the scam, and made the betrayers reap what they sowed. She pulled herself together and ultimately succeeded in developing a new generation of vaccine, guarding all living beings with a kind heart.
