Disco (2020) Plot Summary & Ending Explained

Disco Inferno presents a complex and haunting ending that blurs the line between reality and imagination, leaving it up to the viewer to interpret what truly happened. Throughout the film, we see the troubled spirit of Sister Lynn, a woman consumed by jealousy and guilt over her inability to become a mother, which ultimately led her to commit a terrible sin—killing an innocent woman and taking her baby. Sister Lynn’s spirit remains tied to the church where she died and, later, the abandoned site where the new nightclub, Inferno, is built.

In the film’s climax, we see Mel, who is pregnant, participating in a dance competition at the Inferno club, which stands where the church once was. As Mel prepares for her performance, she begins to experience visions of Sister Lynn, who appears to be seeking to take her baby. It is revealed that Mel is actually the girl from Sister Lynn’s past—her own mother was murdered by the vengeful spirit when Mel was a child, and she was handed over to social services. Now, on the brink of motherhood herself, Mel’s subconscious fears and guilt manifest as a ghostly presence that tries to claim her unborn child.
