Erebus is an anthology horror film inspired by the well-documented history of supernatural phenomenon in Rhode Island. Using Block Island's intimate setting as a backdrop, Erebus centers around the Gorham House, a mysterious old hotel with a torrid history of violent occult activity, as well as supernatural, and paranormal.

Within the bowels of the hotel he harbors a grotesque secret, which unfortunately for him, just got out. "Exposure" - Frank Martin is a 1970s era forensic photographer who is commissioned by the historical society to take on the task of photographing all their properties, starting with the Gorham House. As he begins to photograph the premises his pictures expose malevolent presence and he makes the morbid realization that he is not alone... "Haxan" - When a team of paranormal investigators, in the late 2000s, venture to the Gorham House to investigate the rumored paranormal phenomenon, their pursuit of the supernatural provides their most substantial evidence to date. However, their excitement quickly turns to horror when the contact they establish with the hotel's residents begins to prove fatal.
