Plot Summary

After the sudden death of his wife, former priest Graham Hess (Mel Gibson) retreats into a quiet, isolated life on a Pennsylvania farm with his two children and younger brother. His fragile sense of faith is shaken even further when mysterious crop circles begin appearing overnight in his cornfields.

What initially seems like a cruel prank soon escalates into a global phenomenon, as similar signs emerge across the world. News broadcasts, radio reports, and unsettling eyewitness accounts point toward a chilling possibility: the markings may be evidence of extraterrestrial visitors.

As fear spreads and society teeters on the brink of panic, Graham struggles to protect his family while confronting his own loss of belief. Confined largely within the walls of the farmhouse, the tension builds through silence, shadows, and anticipation rather than spectacle.

Blending intimate family drama with cosmic dread, Signs explores faith, coincidence, and survival in the face of the unknown, delivering a slow-burning thriller that turns the ordinary into something deeply unsettling.
