Amityville Ripper revolves around the horrifying meeting of two legendary characters, each known for their gruesome and terrifying deeds. The film is set in a small town located near the infamous Amityville, which has a dark history of its own.
The story follows Sarah Collins, a young journalist who decides to investigate the eerie happenings in the Amityville area after hearing a series of disturbing rumors. As Sarah digs deeper into the town's past, she uncovers a connection between two notorious figures: The Amityville Haunting, made famous by Ronald DeFeo Jr.'s 1974 murders, and The Ripper, a brutal serial killer who haunted the town in the late 1800s.
Sarah's research leads her to discover a hidden diary written by an ancestor who witnessed The Ripper's killings. The diary reveals that The Ripper made a deal with dark forces, offering his soul in exchange for eternal life. Unbeknownst to Sarah, her investigation and subsequent discovery awakens both The Ripper and the malevolent spirit behind the Amityville Haunting.
As the movie progresses, the small town begins experiencing a series of brutal murders that match the signature of The Ripper. Panic spreads, and the townspeople are left horrified as the bodies pile up. Sarah, determined to put an end to the reign of terror, teams up with a local historian who possesses knowledge about the dark forces associated with the Amityville Haunting.
Together, they embark on a perilous journey to unravel the mysteries surrounding the infamous legends. They discover that the malevolent entity behind the Amityville Haunting has resurrected The Ripper to wreak havoc once again, using him as its instrument of terror. As Sarah and the historian delve deeper into the town's dark secrets, they must confront their fears and fight against the supernatural forces that threaten to consume them.
With every passing day, the killings become more brutal and twisted, and Sarah soon realizes that she herself may be entangled in the malevolent force's plans. As she uncovers horrifying connections between her own family's past and the dark events unfolding in the present, Sarah becomes both the predator and the prey in a deadly game of survival.
Amidst the chaos and destruction, Sarah must find a way to break the curse that binds The Ripper to the town and put an end to the malevolent entity's reign of terror.
