Judy, a brilliant scavenger and mech technician, rescued the seriously injured NCPD commander David from the battlefield half a year ago and transplanted a cybernetic eye for him, but she concealed her identity out of concern. Half a year later, the two reunite, and David arrests her due to a misunderstanding. The two are caught in an intense tug-of-war under the physical coercion of electronic handcuffs and cybernetic body electric shocks. When the vicious supporting female character Lina steals the keepsake, pretends to be the savior and gets engaged to David, Judy leaves heartbroken, which triggers David's frantic jealousy. In the end, Judy reveals the truth through the serial number of the cybernetic eye. David switches to a domineering wife-protecting mode, even going so far as to fake his own death and engage in a gun duel, vowing to protect Judy and their newborn baby to the death.
