The Real End of the Great War is the English title for Prawdziwy koniec wielkiej wojny, a film released in 1957, directed by Jerzy Kawalerowicz.
Roza (Lucyna Winnicka) marries a promising young architect, Juliusz (Roland Glowacki).
They have a blissful life together for the first few months, but then World War II breaks out and Juliusz is deported to a concentration camp soon after.
She meets and falls in love with another man, and tries to put her life back together, but one day, unexpectedly, Juliusz does return - a shattered ghost of his former self, physically crippled and tormented by memories of the camps.
First out of duty, and then out of pity, Roza starts to care for him, but her feelings slowly transform into a kind of revulsion.
