The 27th Day (1957)
Five individuals from the USA, USSR, China, and two other nations are inexplicably transported aboard an alien spacecraft. There, they encounter an extraterrestrial being who presents them with mysterious containers, each containing three lethal capsules. The alien reveals that only the designated recipient can open their container through mental command, granting them the terrifying ability to eliminate anyone within a specified radius by simply speaking coordinates into a capsule. With a countdown of 27 days to decide their fates, the group is returned to their homes, burdened with the power of life and death.
