Based on a true story, an advance party of five scientists is stationed in a bunker on Enewetak Atoll 20 miles from the detonation of the first hydrogen bomb test. They are trapped for 11 hours in a "hot" bunker due to miscalculations as to the size of the blast and the direction of the atomic fallout.

United Press television critic William Ewald gave the production a mixed review. He praised the direction and sets and found the production to be "a gripper" when it stuck to telling the story. However, he wrote that it "stumbled" when it turned to conflict between two of the scientists over the morality of the bomb. Ewald found the latter scenes, with scientists exchanging quotes from Browning and Horace, to be clumsy, dramatically unbelievable, and embarrassing.^[4]
