That evening, Shane discovers a secret vault underneath the garage, which requires exactly the type of key that Julie and Bill retrieved to open. When Bill and Julie arrive home, he and Shane go to the garage, where Shane says he is rethinking his career. The two armed ninjas from before arrive and pull off their masks, revealing themselves as the Chuns - the Plummers' North Korean bakery owning neighbors. Suddenly, Bill knocks out Shane, revealing himself to be a double agent. Mr. Chun binds, gags, and guards the children while Bill and Mrs. Chun take Julie down to the vault. They open the door, but a dangerous security system prevents them from proceeding. Mrs Chun loses her eyebrows to the systems flamethrower.
