While All Germans Sleep (1994)

After 50 year, Marek remembers his dangerous adventure as a 5-year-old, when he and his friend, Itzek left a Polish transit camp one night in 1942 - a few days before their evacuation to Auschwitz - to go get the toys they forgot at the ghetto. Based on Becker's personal memories and his 1980 published short story The Wall.
