Who knew that a summer thunderstorm and a lost little boy would conspire to change single dad Cayce D'Amico's life in an instant? With Luke missing, Cayce ventures into the woods near their house to find his son, only to have lightning strike a tree near him, sending a branch down on his head. When he awakens the next day in the hospital, he discovers he has been blessed or cursed—he isn't sure which—with psychic ability. Along with unfathomable glimpses into the lives of those around him, he's getting visions of a missing teenage girl.

When a second girl disappears soon after the first, Cayce realizes his visions are leading him to their grisly fates. Cayce wants to help, but no one believes him. The police are suspicious. The press wants to exploit him. And the girls' parents have mixed feelings about the young man with the "third eye."

Cayce turns to local reporter Dave Newton and, while searching for clues to the string of disappearances and possible murders, a spark ignites between them. Little do they know that nearby, another couple—dark and murderous—are plotting more crimes and wondering how to silence the man who knows too much about them.
