Season 1

The small, country town of Mullan is devastated by a flood which kills five locals. One year later, the residents are still grappling with the physical and emotional scars. Retired astronomer, Ray, has been forced to move his wife, Gwen, a formerly successful actress, into a care facility due to her worsening Alzheimer's. He's heartbroken that she no longer remembers him. Meanwhile, Gwen's old boyfriend, Max – now a bitter, lonely farmer – still pines for his lost love while struggling to hold onto his farm. A youthful stranger, Sam, blows into town with incredible energy and violent instincts and seduces the baker, Tina, the wife of local cop, Griffo. Sam is inexplicably drawn to 12-year-old loner, Isaac, who's been blindly searching for his "missing" mother, Annie, since the flood. When Ray then discovers that his elderly dog has rejuvenated to her youth after eating something from the garden – in the same spot where Ray's young neighbour drowned - he wonders if can he use this "gift" to save Gwen.
