By tram through the Polish city of Wrocław | DW Documentary

For 140 years, tram line No. 1 has cut through Wrocław, and this film rides it with driver Tatjana Granowska past rebuilt facades and the Oder's grassy banks while passengers talk about their changing city. Among them is a man who lost everything in the 1997 floods and now lives, deliberately, on a houseboat on the same river.
