The Russian Sleep Experiment

"The Russian Sleep Experiment" tells of Soviet Union agents and scientists experimenting on both political prisoners and prisoners of war during World War II, in which the prisoners are kept in a sealed-off room which was filled with an experimental gas to prevent sleep. This mysterious gas turns the prisoners into violent zombie-like monsters. In the end, the commander demands a researcher to enter the room and start killing the prisoners.[12] With one of them uttering "So nearly free" before they die.
