Dragnet (1967)

Sgt. Friday (Jack Webb) and Officer Gannon (co-star Harry Morgan) must find 400 pounds of stolen high-velocity dynamite set to go off somewhere in Los Angeles. Their investigation leads to suspect Donald L. Chapman (Don Dubbins), a neo-Nazi and hate-monger, who readily admits the theft. Chapman, however, refuses to divulge where he has the explosives rigged but hints his aim is to bring integration plans to a halt.

Sgt. Friday (Jack Webb) and Officer Gannon (co-star Harry Morgan) track a young gunman who has two hostages in a car. Suspect Donald Albers (Ronnie Rondell) takes a cosmetics manufacturer and her secretary Janet (Peggy Webber) for a "ride" after successfully getting Janet to withdraw $75,000 from a bank while he held her boss at gunpoint. But Albers forgot to consider Los Angeles' freeway traffic in his plans.

Sgt. Friday (Jack Webb) and Officer Gannon (Harry Morgan) are assigned to investigate an armed robbery in which a fellow policeman is a prime suspect. Officer Paul Culver (Kent McWhirter) had been a member of the Los Angeles Police Department for only 114 days. He was working undercover out of the Narcotics Division when a liquor store near where he was operating was held up. He fit the description of the holdup man as given by an eyewitness.

The police interrogate a suspect (Lee Marvin) they believe to have murdered more than a dozen men.

The investigation into a woman's untimely death leads investigators to a drunk and her former boyfriend.

Friday confronts a jeweler with tape recorded evidence that proves he hired someone to rob his own store.
