Death Tunnel

Five college girls who were attending an initiation party (themed "Truth or Scare") wake up inside an abandoned sanatorium. They are told (via a speaker system within the sanatorium) that they must spend five hours inside, each on a separate floor. The girls are warned that they must survive five ghosts during the night. Each girl finds newspaper clippings from the 1930s, and they learn that the sanatorium had previously been used during the so-called "White plague," and that thousands died from the disease - while many others killed themselves in the hospital. Although this starts off as prank, both the girls and the prankster find themselves in a fight to prevent history from repeating itself. They discover that there is only one way out of the sanatorium - the tunnel underneath the hospital, nicknamed the "Death Tunnel," as it was used to transport all of the bodies out of the hospital.
