Graham Hess and his young son and daughter, Morgan and Bo, struggle to recover from the tragic death of Graham’s wife. A neighbor struck and killed her with his car when he fell asleep at the wheel. Graham’s younger brother, Merrill, has been staying with the family. Devastated and bitter, Graham, a reverend, believes God betrayed him, and he has abandoned his ministry.

Mysterious crop circles appear on the Hess' farm and soon the world over. Alien scouts are spotted, and before long, ships arrive from outer space. With TV and radio their only link to the outside world, the isolated Hess family watch in horror as the alien threat turns into a deadly close encounter. The hostile beings are galactic raiders who harvest planetary life forms. With invasion imminent, the family barricade themselves inside the house. As the aliens are breaking in, they retreat to the cellar.

Continuity mistake: When the deputy sheriff comes out of the house, her ink pen is sticking through the hole in her pocket flap but not in the pocket itself. After she turns around at the car, her ink pen is inside her pocket and not "flapping" loose as it was just a split second before. (00:21:15)

More trivia for Signs

Question: Do the individual aliens have cloaking abilities? It seemed at that the dogs were reacting to something that the people could not see. Were they smelling cloaked aliens? Were they going crazy to protect their human owners and that was misinterpreted as an attack on the people? I thought they are walking around at least invisible at times to do their work without detection. I may be wrong on that.

Answer: The aliens were not cloaked, not invisible. They had a chameleon-like ability to change their appearance to match their background. Recall the alien's fingers turning plaid when he held the boy. They seem to be that green color when not camouflaged. The better senses of the dogs did allow them to detect the aliens. However, one of the effects of alien presence noted in the movie was a change in personality; that is what happened to the dogs.
