Martha Jellneck (1988)

72-year-old Martha Jellneck lives alone in a small apartment in Hamburg. Since she's hampered in walking, she never leaves her home. Her only contacts to the outside world are the young social worker "Zivi" Thomas and a neighbor boy who walks her dog. When Thomas tells her one day that Franz Laub, another one of his clients, is having a birthday, she becomes suspicious; that was also her half-brother's name and date of birth, but he died in World War II.
