The Trigger Effect is a 1996 thriller film directed by David Koepp. The film follows the story of Matthew (played by Kyle MacLachlan) and Annie (played by Elisabeth Shue), a suburban couple whose lives are turned upside down when a power outage hits their town and brings out the worst in their neighbors and friends.
As the power outage continues for several days, the couple is forced to confront the dark side of human nature. They are visited by Matthew's friend Joe (played by Dermot Mulroney), who brings chaos and violence into their home. The rivalry between Matthew and Joe intensifies, and Annie must care for their sick baby, adding another layer of tension to an already stressful situation.
As they struggle to survive in a world without electricity and order, Matthew and Annie are forced to confront the reality that their own friends and neighbors may be just as dangerous as any external threat. The film raises questions about the fragility of civilization and the thin line between order and chaos.
The Trigger Effect received mixed reviews from critics but has since gained a cult following for its realistic depiction of the breakdown of society in the face of a crisis.
