Gert reads in the paper about a wave of thefts in town. The mayor gets the news from the ministerial delegate, who also enlists him for 'operation night-owl', which means they prove as masked robbers how unsafe homes and businesses are,n videotape themselves and take something as proof. They succeed at Gert's and Alberto's, but by that time Van Leemhuizen, acting as mayor, has followed Gert's advice to send out the police. The robbing owls are caught, the loot recuperated and their hard to believe story is questioned.
