Lin Xiaowu, the new security guard in the neighborhood, always carries a dog-eared Anti-Eavesdropping Manual—either tinkering with second-hand devices in the monitoring room or putting up "anti-eavesdropping tips" around the buildings. Until a tiny bug falls out of his grandma's medicine cabinet, he uncovers the truth: a greedy real estate developer has bugged the entire building to force residents out! Facing thugs trying to demolish his grandma's old house on one side and his "amateur" skills of fixing electric bikes on the other, Lin fights with his manual: modifying an old radio into a signal detector, hiding in stairwells to record the developer's plots, even risking swapping bugs with his own "counter recordings". When he slams a plastic bag full of bugs on the developer's desk, he realizes the most powerful "anti-eavesdropping weapon"—the evidence neighbors secretly gave him, and the line from his grandma as she hands him warm congee: "We're not guarding a house—we're guarding the warmth of home."
