After marrying Gu Jingchen, Su Nian discovers through the security camera that at three in the morning, a woman looking exactly like her walks out of the wardrobe. Investigating step by step, she uncovers a cruel truth. Gu Jingchen had imprisoned his girlfriend Shen Muan for five years, and even had Su Nian surgically altered to look like Shen Muan, using her body to conceive a child in an attempt to misappropriate the Shen family's assets. Su Nian collects evidence, joins forces with Shen Muan, and ultimately brings Gu Jingchen's gang to justice, taking back her true self and opening a flower shop to start a new life.
