Riwka is 65 years old. His tour bus breaks down between Warsaw and Auschwitz. In the tumult of conversations in Yiddish, anxiety drives you to overflowing. Régine, the same age, thinks to find her old father, who has come to Paris from the other side of Europe. Vera, an 80-year-old Russian, the only one in the world, has just immigrated to Israel at the end of her life. In search of her lost cousin of sight for many years, from bus to bus, alone, foreign to everything, she is lost until exhaustion. And finally in a last bus, by chance, she meets Riwka.
