After adopting a rescue dog, John and Molly Chester decide to move from Los Angeles to a 240-acre farm in Moorpark, California in order to grow food without the use of chemicals.

Without a farm background, the two get help from eccentric biodynamic expert Alan York. They revive an irrigation pond, build a worm compost facility, tend to an orchard with a variety of fruit, and get a pregnant sow named Emma, who gives birth to more piglets than they'd expected.

However, they find a lot of challenges as well, including California wildfires, saving their crops from snail infestation, dealing humanely and respectfully with coyotes who would like to make a meal of their ducks, and saving an orphaned lamb.
