"The Last Stand" is the last of 15 chapters comprising Dick Tracy's G-Men, a serial produced in 1939 and released in 15 minute cliffhanger style increments.
After losing Robal and Zarnoff in a car chase, Tracy radio's to block all roads, hemming the elusive spy in. Zarnoff makes for a hideout in the hills on foot and G-Men and Police follow. Robal and Zarnoff's men battle the federals in a deadly shootout while Tracy stops Zarnoff from escaping in a plane, instead taking off with him prisoner. Zarnoff sabotages the plane and they land in the desert where the spy knocks Tracy out and ties him up before drinking from a spring of water, not seeing the sign that the water was poisoned by Arsenic. Zarnoff soon dies and Steve rescues Tracy, closing the case.
