The film begins with Graham Hess, a widowed former reverend, living on a farm in Bucks County, Pennsylvania, with his two children, Morgan (played by Rory Culkin) and Bo (played by Abigail Breslin), and his younger brother Merrill (played by Joaquin Phoenix). Graham has abandoned his faith after his wife’s tragic death in a car accident.
One morning, Graham discovers large, intricate crop circles in his cornfield. Initially dismissing them as a prank, Graham soon realizes that the circles are too perfectly formed to be man-made. The news spreads quickly, and the crop circles become a sensation, attracting media attention and curiosity from the local community.
As the mysterious events escalate, Graham and his family begin to experience strange occurrences around their farmhouse. They hear unexplained noises in the middle of the night and witness strange lights in the sky. Graham’s children become increasingly frightened, and he struggles to reassure them while grappling with his own doubts and fears.
Meanwhile, reports emerge of similar phenomena occurring around the world, leading to widespread speculation and panic. Conspiracy theories abound, with some suggesting that the crop circles are the work of extraterrestrial beings.
As tensions rise, Graham’s brother Merrill suggests boarding up the house to protect themselves from potential intruders. Despite his skepticism, Graham reluctantly agrees, and they prepare for a possible confrontation with whatever—or whoever—is responsible for the mysterious events.
In a climactic sequence, Graham and Merrill confront a hostile alien intruder inside their home, using makeshift weapons and strategies to defend themselves and protect the children. Through a combination of courage, ingenuity, and sheer luck, they manage to overcome the alien threat and emerge victorious.
In the aftermath, Graham and his family reflect on the events that have unfolded and the impact they have had on their lives. Graham rediscovers his faith and finds solace in the belief that there are forces at work in the universe beyond human comprehension.
“Signs” is praised for its atmospheric tension, thought-provoking themes, and effective use of suspense. It explores the themes of faith, family, and resilience in the face of the unknown, leaving audiences questioning the mysteries of the universe long after the credits roll.
