Produced by the team behind Coal House, the programme transports the families back to the late 19th century and a completely different way of life in the Nantlle Valley.
They live in two cramped smallholdings in the shadow of Snowdon, looking out over the Irish Sea, and face a daily battle against the elements to put food on the table.
The real-life drama sees them toil the land and sweat the quarry-face as they struggle to cope with ordinary life over a century ago.
But, in an area steeped in tradition, they also receive the support of a network of neighbours - including a sheep farmer, shopkeeper and minister - all played by real-life characters from the surrounding communities.
