S1, E1: British detective and recovering alcoholic Jim Worth is adjusting to the quiet life in the Canadian Rockies after moving from London to the mountain idyll of Little Big Bear with his family – his wife Angela, teenage daughter Anna, and five-year-old son Petey. As the new chief of police, he finds there is little to occupy himself with at work, until North Stream Oil sets up a refinery near the town. Jim struggles to protect his family and the town from the wave of organised crime that follows. When a local doctor who previously launched accusations against the corporation turns up dead, Jim suspects foul play and opens a murder investigation. After Jim’s family suffers a shocking tragedy, dark, dangerous secrets emerge and vengeance arrives in paradise to unleash a very particular kind of hell.
