Six years ago, security guard Lin Guoan smashed a car window to rescue a toddler trapped inside, but the child's father, Zhou Qiming, falsely claimed an expensive watch was lost, accusing the old man of theft and causing him to lose his job and bear six years of infamy. Six years later, Zhou Qiming's property company won the bid for the residential compound where Lin Xia serves as director. Lin Xia withheld the seal to seek justice for her father, but delayed signing out of personal resentment, causing homeowners to pay an extra eighty thousand. After An Sheng entered, it fabricated fees, exaggerated maintenance, and cut off water to force a signature, and on a rainy day even withheld equipment keys to demand a two million authorization. Until Zhou Qiming once again left his own young son alone in a flooded basement, it was Lin Guoan who smashed the window a second time to save a life, causing Zhou Qiming to publicly admit the watch was never lost.
