Greta (1986)

The movie begins with 2 men on a plane from Poland to Germany. They discover that they are bound for the same little town and were there on the same day. The younger man tells his experience as a boy. A 10 yr old boy, Tadek, and his mother have escaped from a work camp near the end of WWII in Europe. They are separated in an air raid. He is found in a pit by a deserting German soldier, who breaks into a house to get them food. Tadek is a pianist and plays a Mozart piece but they are heard by the SS. Tadek hides and the deserter is caught. The SS captain orders him shot and plays the piano while the man is executed and the house is searched. Tadek is caught but escapes. He is found by little Greta. She takes him home where her mother feeds him over the objections of her mother in law. The father returns and he turns out to be the SS captain. He hears Tadek playing the same Mozart piece and knows it's the escaped boy. Afraid of the advancing Russians and of being denounced by the boy, he has him locked in the bathroom. Greta frees him and they hide overnight. Greta takes him into town and Tadek is recognized. While a fellow refugee looks for his mother, Tadek and Greta have a parting with a promise and a kiss that he will not betray Greta's father. The plane lands and the older man begs the younger to finish the story. He doesn't, but the movie ends with the Tadek and an older Greta kissing on the tarmac.
