The film introduces key twists surrounding The Grabber's past and the Blake family history:
- Origin of the Killings: Flashbacks to 1957 reveal that decades before targeting Denver suburbs in 1978, The Grabber (working under the alias 'Wild Bill' at Alpine Lake) committed his first three murders and concealed the bodies in the freezing lake.
- The Mother's Murder: Finney and Gwen grew up believing their mother committed suicide. Gwen discovers that Hope had uncovered The Grabber’s crimes at the camp, leading The Grabber to murder her and stage her death as a hanging.
- The Supernatural Anchor: The Grabber remains anchored to the mortal realm because the bodies of the three boys were never found, allowing their trapped souls and unresolved terror to empower his spectral form.
During the blizzard climax, Finney, Gwen, Ernesto, Armando, and their father Terrence chop through the frozen lake to retrieve the submerged remains. Simultaneously, The Grabber traps Gwen in a dream-state confrontation. Aided by the three trapped spirits, Gwen resists him until the physical ice is breached. Once the remains are surfaced, The Grabber loses his spectral anchor, his mask shatters, and Finney destroys the specter with an axe blow. Afterwards, Gwen answers one final payphone call from her mother's spirit, who reassures her that her abilities are meant to bring light into darkness.
