As they travel through minefields both real and imagined, Robert and Attila grapple with sibling rivalry, family secrets and incalculable loss. Along the way they encounter mysterious fellow travelers, bewildering sights of a nation in transition and surprising hilarity, all in pursuit of the one place they thought they'd lost forever: home.
