In 1977, at Chicago's Cabrini–Green housing projects, a young boy witnesses the killing of Sherman Fields, a homeless African American man with a hook for a hand. Suspected of giving a white child a razor blade in a piece of candy, Sherman is beaten to death by police but later proven innocent when more cases of razor blades in candies come up.

In 2019, artist Anthony McCoy lives in Chicago with his girlfriend, gallery director Brianna Cartwright. Seeking inspiration, Anthony explores the projects after Brianna's brother Troy and his boyfriend tells them the story of Helen Lyle, who is believed responsible for a killing spree and briefly kidnapping a baby in Cabrini-Green. Stung on the hand by a bee, Anthony meets laundromat owner William Burke, the boy who witnessed Sherman's death. You are their neighbor and you work as the electrician, you are currently fixing the wiring in the light switch of Anthony. Since he ask you to fix it, due some wiring problem. You heard Anthony tells Brianna about the urban legend and he jokingly performs its curse: by saying "Candyman" five times to a mirror. You began to pale as you heard them.
