The Lin family, the nation's most powerful dynasty, has spent a lifetime searching for their lost grandson and heir. Lin Mo, the rightful successor, knows nothing of his heritage and has struggled by as an orphan. By chance, a drunken Lin Mo rescues runaway campus beauty Su Yuting, who—to defy an arranged marriage with the Lin family—sleeps with him. Lin Mo, blackout drunk, remembers nothing, and soon begins dating Chen Xiaotong. The money-hungry Chen Xiaotong dumps him for wealthy playboy Gu Pengfei, and when Lin Mo confronts them, he is humiliated—just as Su Yuting calls from the delivery room begging for help. Stunned to learn the campus beauty is about to give birth to his child, Lin Mo rushes to the hospital. After the birth, his devoted care moves Su Yuting deeply, but Chen Xiaotong and Gu Pengfei expose the affair to the Su family and, scheming to climb into the Lin family's favor, relentlessly target Lin Mo and Su Yuting. To protect his wife and child, Lin Mo takes several knife wounds—until the Lin patriarch arrives in the nick of time, and Gu Pengfei and Chen Xiaotong finally get what they deserve.
