After the apocalypse, which came in the form of a deadly flu virus that wiped out everyone he cared about, along with much of the rest of the world, Hig lives alone with his dog in an abandoned airport hangar, where he keeps himself alive with provisions and keeps his airplane, a 1956 Cessna, fueled and air-worthy. Sometimes he takes the plane in the sky to places where he can fish and pretend the flu never happened, with his dog as the copilot. One day he hears a garbled radio message--and hope springs in him that there might be something like the civilization he once knew out there. Risking everything, he takes his dog and plane, and flies off in search of the radio signal.
