After a string of mysterious disappearances and horrifying encounters take place in Northern California, Game Wardens and Officers are less than surprised when six-year-old Tyler Jacobs vanishes by the South Fork Eel River while fishing with his family. As the family is riddled with guilt and on the verge of losing hope, Native Americans from the local Yurok Tribe step in to help spread light on the recent events. Embarking on a daunting journey through the vast wilderness and majestic Redwood Forest in search of his son, Randy Jacobs soon learns that what he once thought was just a myth may actually be a living and breathing creature after all. With a dangerous winter storm approaching and still no sign of his son, the clock rushes forward. Can he find him before it's too late?
