About the title
The 1980s. A group of medical students conducts research on the effects of prolonged sleep deprivation on the body. Something goes catastrophically wrong with the test subject, and their department is shut down. But this doesn't stop the intrepid researchers of the dark sides of existence — the friends decide to experiment on themselves. To stay awake for 200 hours, they use a certain substance, and soon discover that something sinister is beginning to stalk each one of them.
