Radio Patrol

Pat Bourke and his friend, Bill Kennedy, train together at a big city police academy, which is overseen by Tom Keogh, a stern but fair sergeant. One day, an instructor at the school directs Bill to arrest Kloskey, a fellow student known for his surly, reticent behavior. Bill believes the arrest is part of a drill but later learns that Kloskey is a cohort of "Little Ernie," a notorious gang leader. After questioning him, Keogh releases Kloskey but orders him to leave town. Six months later, Bill, Pat and another friend, Pete Wiley, graduate from the academy. At their graduation ceremony are Pete's garrulous girl friend Vern and Sue, Pat's fiancée. In spite of her attachment to Pat, Sue actually prefers Bill and marries him. A year later, Pat and Bill, who are still friendly, are assigned as partners to Radio Car #32-W and are given the stockyard patrol. After Koegh, now a lieutenant on the force, demands that his men redouble their efforts to bring in Little Ernie and his gang, Pat discovers that Bill has been accepting graft from a local boardinghouse keeper. While Pat lectures Bill, a call comes in, ordering them to a tenement where a murder has been reported. As they arrive at the tenement, they see Pete rushing up the stairs to the crime scene. Before Pete reaches the top, he is shot and killed by a drug addict, who then turns on Bill. Pat saves Bill, killing the addict with his gun. While Vern mourns Pete's death, a pregnant Sue frets for the safety of her husband. On the night Sue leaves for the hospital to have her baby, Little Ernie plots to break into a stockyard safe. While one of the gangster's cohorts makes a series of phony calls to distract the police, Bill pleads with Keogh to be relieved from duty. Keogh refuses Bill's request, however, and sends him on his stockyard beat with Pat. Bill takes the long route to the yards and makes several calls to the hospital along the way. Already at the stockyards are Keogh and a special police detail, who burst in on Kloskey and other of Little Ernie's gangsters during their safecracking attempt. Although the gangsters gun down all of the police, Keogh manages to alert police headquarters before dying. When Bill and Pat finally arrive and find Keogh dead, Bill confesses to Pat that he accepted $2,000 from Kloskey to stay away from the yards. Furious, Pat begins to choke Bill, unmoved by his claims that he took the payment because of Sue and the baby. During Pat's outburst, the safe blows up, and Pat and Bill return their attention to Kloskey, charging the building with their guns blazing. Although Bill is shot fatally, Pat continues his assault and finally kills Kloskey. Later at the hospital, Sue, still hazy from anaesthesia, mistakes Pat for Bill. Overcome with emotion, Pat says nothing to Sue but pleads with her doctor to save her newborn's life.
