It is Caleb's sixth birthday, and his father Sean has spent the morning setting up the house for the party. Five hours pass. It is time to cut the cake, and Caleb is not there. He is not anywhere Sean can find him. A call to the police starts the official search, but Sean does not wait — he begins his own. A storm is arriving in three days. The time limit is real. Three days to hang missing person posters across the area, build a shelter before the weather arrives, and find where Caleb went.
