Earth, Again – Details, episodes & analysis

Ten years after humanity was forced back to a permanent pre-electric age, sixteen-year-old Liv learns her pacemaker battery is failing. Her father Robert — a former NASA engineer — leads a desperate thousand-mile horseback journey across Montana, Idaho, and Washington to reach a secret military prototype that might save her life. What they find at the end of the road will matter as much to the human race, as it will to Liv.
