Dick Tracy's G-Men (1939) is a 15-Chapter Republic movie serial based on the Dick Tracy comic strip by Chester Gould. It was directed by William Witney and John English.

Plot

International spy, Zarnoff, in the employ of "The Three Powers" (presumably a fictionalized reference to the Axis) is captured by Dick Tracy at the start of the serial, tried and sentenced to death. However, through the use of a rare drug embedded by his agents in the evening newspaper, he escapes from the gas chamber. His men pick up his "corpse" by ambushing the hearse and administering another counter-drug. He continues his espionage plans, while taking the opportunity of revenge on Tracy.
