When the U.S. government finally tracks them down, the off-the-grid Fox family flees to begin a new life.

The Foxes enlist the help of two coyotes who promise to take them across the U.S. border into Mexico.

With the Feds closing in on them, the Foxes and Chuy must cross the desert on foot—and face adversity both natural and man-made.

The Foxes seek refuge in an opulent hacienda, where a family's all-powerful matriarch sees them as pawns in her own game.

Arriving in Mexico City, the Fox parents attempt to connect with Allie's mysterious contact while the kids get into trouble.

Held captive by a shadowy organization, Allie and Margot must find a way to escape and get back to their kids.
