Fu Xiao is cold and taciturn, yet a ruthless figure who clawed his way out of a mountain of corpses and a sea of blood. To investigate an unsolved case, he enters the wealthy Pei family in someone else's place as a bride, becoming the "wife" of Pei Yanzhi, a disabled young master. Everyone assumes he's a pushover anyone can bully, until someone sneaks into the bridal chamber in the dead of night. Fu Xiao twists the intruder's jaw off with a backhand, only to discover that every corner of the Pei household is haunted by secrets. His gentle, considerate stepmother secretly keeps assassins in her employ, his innocent and lively younger sister-in-law is an information broker behind the scenes, and his "husband," sitting in a wheelchair, always offers him a handkerchief after he kills someone and softly asks, "Wipe your hands?" Just when Fu Xiao finally pins down a clue to the murder, he realizes he stepped into a trap Pei Yanzhi set long ago. This disabled man is the hunter hiding deepest of all.
