DJ MacDonald is a normal high school student in Guelph, Ontario. Like many fourteen-year-old Canadian boys, DJ's life revolves around hockey, but he is not as normal as he appears. Tormented by vivid visions of strange creatures, and haunted by apparitions from another world, DJ leaves for a family reunion in the Philippines.
When DJ returns to his roots, he and his cousin Hans discover a seashell shaped like a crown near the dock. Just as Hans holds the shell over DJ's head in a mock crowning ceremony, a bright light from the moon zaps the two boys. Suddenly, DJ and Hans are mysteriously transported to the bottom of the ocean in an air bubble where they come face-to-face with monstrous sea ogres. It is only after returning to the safety of the dock that DJ learns of a family secret. As DJ leads a Malipayon warrior mission to rescue a dying prisoner held captive somewhere in the deepest ocean chasm, only time will tell if faith, honor, and magic spells will be enough to overcome the evil that lurks beneath the sea.
