In Chicago, a blue-collar worker named Tom Witzky leads a normal, if unremarkable, life with his wife Maggie and his son Jake, who appears to have the ability to communicate with spirits. One evening at a party, Tom skeptically agrees to be hypnotized by his sister-in-law, Lisa, who is known for her interest in psychic phenomena. The hypnosis unexpectedly opens his mind to a previously untapped realm, imbuing him with an ability that drastically alters his perception of reality. Following the session, Tom begins to experience disturbing visions and hears eerie whispers that he cannot explain, leading him to believe that his home and neighborhood are haunted by a malevolent presence.

The sudden onset of supernatural experiences drives Tom to obsess over the meaning behind the cryptic messages and spectral appearances, particularly the persistent vision of a mysterious young girl who seems to be reaching out to him from beyond. His obsession with deciphering the cryptic messages disrupts his family life, straining his relationships with Maggie and alarming them with his increasingly erratic behavior. As he delves deeper into the unsettling mystery, his search for answers pulls him into a dark and tangled web of secrets lying at the heart of his seemingly tranquil community. Tom's quest not only threatens his sanity but also forces him to confront uncomfortable truths about the people closest to him and the fabric of his reality.
