When an unidentified sea creature begins terrorizing his hometown, Calvin must fight to hold his close-knit community together. Determined to keep his son Wade (Heaton) and the rest of his family safe, he teams up with a visiting marine researcher (Davis) to confront the creature and reveal the island’s buried secrets before it’s too late.”
