Old Bliss

Six years after the world fell to the dead, Adam survives alone in a fortified scrapyard, building a bus he calls Old Bliss to escape the ruins of East Tennessee.
A chance encounter at a deserted bus yard forces him to take in Whitney and her twelve-year-old son Wilber, disrupting the isolation that's kept him alive.
As the dead close in and raiders stalk the hills, Adam must decide whether to keep running or build something worth protecting.
But survival isn't simple - not when the real fight might be against his own mind.
