Dragnet was a groundbreaking American radio series that revolutionized the police procedural genre, created and starring Jack Webb as Sergeant Joe Friday. Known for its documentary-style realism and authentic portrayal of police work, this milestone episode 200 follows Friday and his partner as they investigate a gang of professional safe burglars operating throughout Los Angeles. The case takes an unexpected turn when the criminals are brought down by something as mundane as an unpaid-for trench coat, demonstrating Dragnet's signature style of showing how small details often lead to solving major crimes.
