The Amityville Harvest follows documentary filmmaker Christina and her team as they investigate the notorious Amityville house and the surrounding area to uncover the truth behind the rumored liquor-smuggling operation that took place there during Prohibition. The team stays at an aging manor owned by the mysterious and elusive Vincent, who claims to have information that can help them uncover the truth.
However, strange things begin to happen as soon as they arrive at the manor. Despite numerous attempts to capture his image and voice on camera, the crew is unable to record anything related to Vincent. This leads them to suspect that there is more to him than meets the eye.
As Christina and her team explore the manor and the surrounding area, they experience shocking nightmares and encounters with blood-thirsty creatures. Despite these horrifying experiences, the crew members cannot resist Vincent's hypnotic charm and find themselves falling deeper under his spell.
As the team delves deeper into the history of the Amityville house and the region, they begin to uncover dark secrets that have been hidden for decades. Eventually, they realize that their quest for the truth may have put them in grave danger and that the only way to survive is to escape the manor and the grasp of Vincent before it's too late.
