This is a "live" episode of the long running anthology series, "Suspense". "Suspense", which ran for 260 episodes between 1949 and 1954, was a television off shoot of the popular radio series of the same name.
This one takes place at Yucca Flats just before an atomic bomb test. The army has built several buildings etc at the sight of the upcoming blast. They want to see what damage the explosion will cause. They are putting life like mannequins in the buildings.
O.Z. Whitehead, the supplier of the mannequins is running a bit late on delivery. He has 8 hours to get them all in place. The officer in charge is giving him a bad time about the delay. Whitehead returns to his shop to finish the dummies. His, wife, Louise Larabee, is also there. Larabee is not amused with her lot in life. She considers Whitehead a failure and rides him hard. Complain, complain, and complain is the only thing that makes her happy.
Whitehead finishes his work and loads up the mannequins for delivery to the bomb site. The wife decides to tag along in order to keep up the non-stop nagging.
Larabee gets bored on the drive out and pops a couple of her nerve pills. She is soon fast asleep. Whitehead makes it through the several guard posts to the house. He carries in all the mannequins and sets them up in their assigned spots.
As he drives off we see that there is a mannequin now sitting in the front seat instead of Larabee. Whitehead has had his fill of the dear wife. He placed her inside the soon to be destroyed building with the mannequins.
Back at his shop, Whitehead starts to have second thoughts about what he has done. Back in the car and off he roars to retrieve the shrew. The problem here is he only has 90 minutes to get there, and then back to safety. He roars through the check-stops and reaches the house. He grabs up Larabee and heads back to the safe zone. They only have 25 minutes to evacuate the blast zone.
Do they make it?
