They call it Sleepy Hollow. A small village in Kazakhstan which has succumbed to a mysterious ailment – its dwellers keep falling asleep for no apparent reason. The indiscriminate illness has no cure. Episodes begin without warning, and those affected never know if they will wake up again. Some blame ghosts, others the closed uranium mines located nearby. But despite multiple attempts by medics and scientists to solve the riddle, the causes and consequences of the disease remain unknown. Now the RTD team goes to Kalachi village to undertake its own investigation.
