To unplug from the modern world, Brett Hines moves his family from the suburbs to the untamed wilderness of central Washington. Setting up their new home in a race against winter, they come face to face with their first off-grid hurdle: predators.

To create a sustainable food system, the Hines start building a greenhouse and Brett sends Drew and Sarah to retrieve a massive trailer that will become a root cellar. But the trip up the mountain proves harrowing.

The threat of fire season pushes Michael to lead construction on the root cellar while Nathan and Joshua craft a water truck, and Ariel makes a tasty treat to beat the heat.
