DJ is always thrilled to spend time with his grandfather, a person he idolizes. When his grandfather announces that he's going to take all of his grandsons on individual adventures, it seems only fair that DJ, as the oldest grandchild, will get his adventure first. An adventure that sees his grandfather at the controls of a small plane as the two fly to Central America for a week. But when someone tries to kidnap him, DJ must flee through the jungle and down a crocodile-infested river, pursued by armed gunmen. When he isn't busy trying to stay alive, DJ discovers things about himself he never suspected and uncovers information that leads him to believe his beloved grandfather is living a secret life.
