When strange tides begin disrupting the quiet fishing town of Greyhaven, Jonah Calder and a researcher named Mira discover that an ancient creature known as the Sleeper has awakened beneath a deep ocean trench. The guardian rises because a powerful hunter from the open ocean has entered its territory, triggering a violent battle in the stormy sea just beyond the harbor. As the townspeople watch helplessly, the Sleeper defeats the hunter and returns to the depths, revealing that the town has unknowingly been protected for generations by a hidden guardian beneath the waves.
