The signal appears to affect anyone who hears it, overriding normal parental instincts with violent intent. The source of the transmission is never identified, leaving the cause ambiguous.

Foreshadowing: The opening scene shows a mother placing her car on railroad tracks with her child inside, establishing that the hysteria has already begun before the main story.

Immediately after giving birth, Jenna hears the transmission and becomes violent, attempting to harm her newborn baby. Kendall barely escapes and witnesses the widespread chaos as the signal affects other new parents in the hospital.

Foreshadowing: The static signal has already caused violence at Carly's school and in the Ryan household, showing it spreads through any audio or video device.

Damon survives the initial attack from Brent but is later severely injured when Kendall awakens from the explosion and attacks him with a knife. While the film ends with Damon still alive alongside Carly, Josh, and their restrained parents, his condition is dire and uncertain. The ambiguity leaves his ultimate fate unclear.

Foreshadowing: Damon earlier confesses to killing his own father in self-defense, establishing that he will do whatever it takes to survive.

The housekeeper has already been affected by the static signal before arriving at the Ryan home. When she enters with Josh present, the signal's influence causes her to attack her own daughter with a meat tenderizer. This shocking scene demonstrates that the hysteria affects all adults, not just parents, and is already widespread before Carly even learns about it.

Foreshadowing: The film's opening establishes the hysteria through the mother on the railroad tracks, showing the phenomenon began earlier.

Carly discovers Brent and Kendall's plan to poison her and Josh by running a hose from the oven gas into the basement. She sets up a trap using matches at the door. When her parents break through, the gas ignites from her lit match, creating an explosion that knocks Brent and Kendall unconscious long enough for Carly, Josh, and Damon to escape.

Foreshadowing: Earlier in the film, Carly demonstrates her quick thinking by escaping the school mob and finding safety, showing she is resourceful under pressure.

Brent's parents arrive at the house expecting a normal dinner, but they too have been exposed to the static signal. Like all affected adults, the transmission triggers violent impulses against their own family members. Their attack on Brent marks the final collapse of family bonds, as even grandparents join the murderous frenzy.

Foreshadowing: The pattern of the hysteria spreading from parent to parent throughout the film suggests no adult is immune.

In the final moments, Brent begins to say "But sometimes, we just want to, " before the screen fades to black. The statement implies that beneath the signal's influence, there may be buried resentment or dark thoughts that parents sometimes have about their children. Whether this reflects the signal's truth or is simply the ranting of a disturbed mind remains deliberately ambiguous, leaving the horror unresolved.

Foreshadowing: The film establishes early that Carly resents her father's disapproval and that family tensions exist, though the statement goes far beyond typical parental frustration.

When parents storm Carly's school with violent intent, Carly and her best friend Riley manage to flee through a window. However, their escape is short-lived because Riley's mother arrives and strangles her own daughter in front of Carly, demonstrating how quickly and personally the hysteria affects victims.

Foreshadowing: The static begins disrupting electronics at Carly's school right before the attack, giving warning of the incoming chaos.

The static signal broadcasts through all electronic media, televisions, radios, car radios, and hospital equipment, simultaneously affecting anyone who hears it. This explains why parents across town attack their children at roughly the same time. The film never explains who or what transmits the signal, making it an unexplained global event.

Foreshadowing: The mysterious static disrupts electronics throughout the film, always preceding or accompanying violent episodes.
