South African 'ghost hunters' venture into the night looking for answers

For a little over a year, 'The Upsidedown', a group of paranormal enthusiasts, have been seeking out the ghosts and spirits trapped in the dark corners of the South Africa's complex and violent history. Using technology, including infrared cameras and motion detectors, the team search an abandoned university building that housed a mortuary during the 1980s, and where guards have reported unexplained noises in the night.
