Time is running out for movies that can plausibly be about present-day old people intercut with flashbacks of their youth in the second world war. This one is about a (very) old piano teacher, Frau Krüger, played by Monica Bleibtreu, a cantankerous martinet who teaches the instrument to inmates of a women's prison. Underneath the harshness and the severity there is a thick, spongey layer of pure Hollywood schmaltz, and the movie runs on predictable lines.
