The cryptic signals give him something to focus on instead of confronting his personal loss, and his investigation becomes a way to avoid dealing with his unresolved grief.

Hannah is James's missing wife who disappeared before the events of the film. The ending reveals that James has been living with unresolved grief and guilt over her disappearance. While the film never clarifies exactly what happened to Hannah, her absence is the driving force behind James's psychological unraveling and his desperate search for answers in the broadcast mystery.

Michael Gardner is a man James tracks down after finding the third tape, believing him to be the kidnapper responsible for the missing women. James kidnaps and records Michael, possibly killing him in his delusional state. The film deliberately leaves ambiguous whether Michael was actually involved in any crimes or if James's deteriorating mind manufactured this connection. The uncertainty reflects the film's central theme of blurred reality.

In the film's final moments, James shoots a masked woman crossing the road while experiencing severe hallucinations and distorted perception. It remains unclear whether this woman was real or entirely a product of James's unraveling mind. The scene is intentionally ambiguous, suggesting that James may have committed a terrible act while lost in delusion, or that this too is a hallucination.

The film never confirms whether the masked woman James sees crossing the road is real or a hallucination. Given James's severe mental deterioration and the earlier hallucinations of his wife Hannah, the scene is deliberately ambiguous. This uncertainty reinforces the film's central question of what is real and what exists only in James's mind.

The third tape leads James to the farmhouse where Michael Gardner is located. The exact contents of the tape are not fully detailed in the ending, but it provides the location that James interprets as proof of the conspiracy and the kidnapper's identity. However, given James's mental state, it's unclear whether the tape contained actual evidence or if James was projecting meaning onto ambiguous material.

James kidnaps Michael because he has become completely consumed by his need for closure and answers. After months of investigating the broadcasts and the missing women, James has constructed a narrative in which Michael is the perpetrator. Driven by compulsion and delusion, James believes he is finally confronting the truth, even though he is actually acting as a dangerous vigilante rather than a rational investigator.

The film deliberately leaves the entire ending ambiguous, never confirming what is real versus what is James's hallucination. The evidence suggests that James's mental state has deteriorated to the point where he can no longer distinguish between reality and his own delusions. The ending implies his entire investigation may have been a way to process his grief rather than uncover actual facts, and his quest for truth led him into irreversible madness.

The broadcast signals remain largely unexplained, though they are tied to historical missing persons cases. The film suggests the signals may be connected to real crimes or may be deliberately mysterious. However, the ending implies that their meaning matters less than what James's obsession with them reveals about his own psychological state. The signals become a mirror for his unraveling mind.

James's search was doomed because he was using the investigation to avoid confronting his actual trauma: the loss of his wife Hannah. Rather than processing his grief, he poured his energy into an unsolvable mystery that gave him purpose but no resolution. The ending suggests his quest was always more about escaping his pain than finding objective truth, and this psychological foundation made finding real closure impossible.

The twist is the revelation that James's entire investigation has been driven by his unresolved grief over his missing wife Hannah rather than pure journalistic curiosity. His obsession with the broadcast signals and missing women is revealed to be a coping mechanism that has spiraled into delusion. The final twist is that James himself may have become the monster he was hunting, potentially killing an innocent man and shooting an unknown victim.
