While out fishing and picnicking with her family near their home at Niagara Falls, seven-year-old Abby wanders off and encounters a young, abused boy, hiding in the woods. A couple throw the boy into the trunk of their car and abduct him. Traumatized and scared, Abby remains silent about what she witnessed.

Now an adult, Abby returns to Niagara Falls following the death of her mother. Throughout her adult life, Abby has had various problems, one of them being a compulsive liar. Her mother has left a now defunct motel, The Rainbow, to Abby and her sister, Laure. Laure wants to sell the motel to a prominent local family, however Abby is reluctant to do so, still obsessed with the abduction of the "one-eyed boy".

Abby begins to investigate the mystery of the boy in the woods. She soon discovers his name, Alex Moulin; the son of a husband-and-wife magical act known as the Magnificent Moulins. Following their son's disappearance, the Moulins moved to America.

Abby meets local conspiracy theorist and podcaster Walter Bell, who is of the opinion that Alex did not commit suicide, as no trace of his body was ever found. He's always held on to strong suspicions that the powerful Lake family was responsible for boys' disappearances in the past.

To continue with her investigation, Abby requires access to Charlie Lake's office; she pretends to have signed the papers authorizing the sale of the motel (she has, in fact, signed them in disappearing ink). While at his office she sees a photo of the Moulins and a woman, Beverly Mole, who worked with them as an animal trainer. Apprehensive of Abby's inquiries, Charlie makes ominous threats causing her to rush out in fear.

Abby makes contact with Beverly Mole, luring her with casino access along with free hotel accommodation at The Rainbow. Beverly arrives along with her husband Gerry. While Beverly is gambling, Abby attempts to dig up more information, but Beverly returns to her room early after a dispute at the casino. She angrily leaves.

Abby uses her sister's passport to travel to America to see the Magnificent Moulins magic show. After the show, a strange encounter occurs between the three of them. Upon returning home to Canada, the authorities discover Abby's stolen passport and arrest her.

Still undeterred and determined, Abby breaks into Beverly's house where she finds Gerry chained up. He confesses that he and his wife kidnapped Alex, with the intent to blackmail the Moulins. The police arrest Beverly and rescue Gerry, finding crucial and incriminating evidence.

After Gerry's confession, the case garners a media frenzy. Charlie Lake is soon arrested, all the while proclaiming his innocence in Alex's murder. The Moulins manipulate the media attention, pleading their ignorance and innocence of any wrong doing against their son, while making threats of slander lawsuits.

Life in town returns back to normal and Abby moves on, now employed at another, more up-market motel. A man with an eye patch walks in to rent out a room for an indefinite amount of time. Appearing to be not much older than Abby, he asks if perhaps they've met before. Noticing a newspaper on the desk with Charlie's picture, the guest tells Abby that Lake is not lying and states that in fact, he saved that boy's life. Abby stares after him in wonderment as the man walks away from the reception area towards his room.

The film was based in part on Shin's own life; his parents formerly owned a motel in Niagara Falls, where Shin has childhood memories of witnessing what he understood at the time to be a kidnapping.^[6] However, during the making of the film, he faced resistance from the Clifton Hill business improvement association, because the organization feared that the film would paint the city and the district in a negative light.^[6]

The film premiered at the 2019 Toronto International Film Festival under the title Clifton Hill.^[5] IFC Midnight obtained the U.S. distribution rights to the film and released it on February 28, 2020.^[7]
