Ghosts of Darkness (2017)

Two paranormal investigators are unexpectedly thrown together in the hope of solving a 100 year mystery. Locked for three nights in a house with a dark and unsettling past, the two investigators must put their differences to one side and work together. They soon discover the myths and stories are nothing compared to what actually resides within the eerie walls of Richwood Manor. Scepticism and showmanship are soon put to one side when the two investigators realise there is more at stake than just their professional reputation. For once they have stumbled onto the real thing, but this time it's their own lives at stake.
