In what turn out to be the last hours of civilization as we know it, Arthur Leander, a famous Hollywood actor, has a heart attack onstage while performing King Lear.

Twenty years after the Georgia Flu kills 99.9% of the population, Kirsten has found a home with the Traveling Symphony, a troupe of Shakespeare actors and musicians.

Rewind to Arthur Leander's last days on earth, when he reconnects with his long-lost love, Miranda Carroll, a self-contained artist who's just finished her life's work.

Danger greets the Traveling Symphony as they head to their next destination: The stranger Kirsten warned about turns out to be a cult leader ravaging local towns.

En route to his funeral, Arthur's ex-wife, Elizabeth, and son, Tyler, are grounded at a small airport with his estranged best friend, Clark.

Amid the wreckage of a deadly attack on the Symphony, Kirsten tries to track down the cult leader--whom we now recognize as Tyler Leander.
