Los Angeles trembles under the shadow of a mad killer who leaves his calling card—a red brick—at every murder scene. With no fingerprints and no clear motive, Sergeant Joe Friday and Ben Romero follow a trail of terror to catch the slayer before he strikes again. This chilling tale of a city's relentless pursuit of justice is one of Dragnet’s most harrowing cases. Originally aired: September 24, 1949.
