Escape's "Zero Hour" is an adaptation of a Ray Bradbury story about a peculiar game played by young children.
It is a typical day in the New York home of the Morris family, and Mrs. Morris is busy with her usual routine. Her daughter, Mink, as well as all of the other young children, are intensely occupied by new, mysterious game called "Invasion." Mrs. Morris isn't bothered by the game until she gets a call from her friend in Connecticut and finds out that all of the kids are playing it there as well. When she learns that the game's "zero hour" is to be at 5:00 p.m. that day, she does begin to wonder what the kids are really up to. None of the other parents are worried about it, but they should be. The children have learned the game from the Martians that are planning to take over the Earth.
According to Martin Grams in Suspense: Twenty Years of Thrills and Chills, "Zero Hour" disturbed many listeners when it aired on Escape and CBS received thousands of letters and phone calls in response. Suspense brought the story back to the airwaves two years later on April 5, 1955. Isha Ashdown and Paula Winslowe returned to play the same roles. John Dehner again appeared as the narrator. Antony Ellis again produced/directed.
Suspense aired this story for the last time on January 3, 1960. Francie Meyers played Mink and Ginger Jones played Mrs. Morris. Stuart Metz was the narrator and Paul Roberts produced/directed.
