The idol of Jack Keller's childhood was Icarus - the conqueror of heights, the hero of Greek myths, who flew too close to the Sun. Jack himself experienced a painful fear of heights after a maniac killed his mother in front of the boy’s eyes, throwing the woman out the window of the seventeenth floor of a skyscraper, and then tried to do the same to Jack. Thirty years have passed since then, and Jack Keller, a happily married, successful businessman, has almost managed to forget about the tragedy that happened to him in childhood. However, the past comes back in the most terrible way. Someone who knows about Jack's childhood nightmares deliberately turns his life into hell by killing people close to Keller. And to win the fight, Jack Keller will have to not only find the criminal, but also conquer his fear of heights.
