Enter the unsettling world of "The Dark Within," a psychological horror that blurs the lines between nightmares, reality, sanity and madness.

Alex Parker, a financial analyst in his late 20s, has built a new life in Chicago, far from his dark origins as the son of a serial killer. But the past has a way of catching up, especially when the present is haunted by life-like nightmares. Alex's dreams transform into vivid, terrifying experiences of murder that eerily reflect the grisly actions of the "Chicago Slicer," a new terror stalking the city.

As these nightmares invade his waking life, Alex's grip on reality slips. His close friends, including Maya, who is desperately searching for her missing brother Liam, become unwittingly involved in his spiraling descent. When Alex's nightmares start to predict real events, like the disappearance of his friend Ben, he's forced into a harrowing self-investigation. Is he a victim of his own fractured mind, or is there a malevolent force at play?
