Well, the plot is roughly following: Józia (read:Yoozhia) is a daughter of a female trade union activist in 1929 Poland. Mother is invited to a congress in the USSR, but a problem arises, namely nobody can care for daughter. The solution: Józia stays for 10 days at home alone, and except of that she must pretend her mother is home, because her mother´s journey to USSR was illegal. No wonder she looks sad:-(((
Thank you Kissonline for bringing the Polish-language version here, a good complement to the German that was already here! This Polish / East German movie has mostly Polish actors and it looks (lip-reading) like the dialog spoken onset was (mostly) Polish, but the German dub is so good that it is hard for me to tell.
I too would like it in HD but I have not found it. I would also like subtitles, but for a TV movie that is just not likely, and I have not found them either. But then there seems to be very little dialog, so perhaps it does not matter too much.
