Daekwon, the leader of a surveillance unit, is facing the threat of a demotion. His current assignment involves posing as an unemployed family head to keep a close watch on a politician’s family, who have been placed under house arrest immediately after returning from overseas. Alongside his team, who have taken up residence next door under the guise of being neighbors, Daekwon uncovers a series of secrets. By eavesdropping on every sound and observing the family’s suspicious activities, from requests to a radio show to mysterious noises in the dead of night, the team gradually pieces together the hidden truths.
