Dakota, an ex-service dog, joins single mum Kate (Abbie Cornish) and her daughter Alex (Lola Sultan) to live on their small-town family farm. Dakota quickly adjusts to her new home and becomes somewhat of a local hero, soon becoming inseparable from Alex. But when the farm's existence is threatened by the town's rogue sheriff (Patrick Muldoon), Dakota must help the family band together and save the land.
