Josh Hartnett leads the cast of a new six-part Canadian thriller set in the coastal community of Snook’s Arm, Newfoundland, where residents face the threat of an ancient sea creature reminiscent of the legendary Loch Ness monster. The series opens with a prologue depicting the mysterious leviathan killing the protagonist’s father, an event that casts a long shadow over the story, as the creature resurfaces four decades later, this time endangering one of the protagonist’s own sons.

Hartnett portrays Calvin, a fisherman who has shifted his livelihood from traditional fishing to harvesting icebergs, which are sold to a local brewery. Despite the challenges of his occupation, Calvin seeks to reunite his estranged children by encouraging them to return to their hometown. The narrative explores the intersecting tensions within the community, including a contested resettlement proposal that promises economic benefits for some villagers but is met with opposition by Calvin.

The series also weaves broader environmental themes into its storyline. The increasing fragmentation of local ice masses, driven by climate change, creates an ironic economic opportunity for Calvin’s iceberg-harvesting venture, while simultaneously alarming scientists observing the ecological damage. Mackenzie Davis plays Fonda, a scientist who emerges as an unexpected ally to Calvin, underscoring the complex relationship between economic survival and environmental stewardship. The show blends elements of thriller and creature-feature genres, highlighting the challenges faced by a remote maritime community navigating both human and natural threats.
