A story spanning three generations, from 1871 to 1945. When Gustav Wengler, a farmer’s son, returns from the Franco-German war in 1871, he goes to work for a precision mechanics and optical company, where he soon becomes a master craftsman. Wengler loyally promises the owner on his deathbed that his sons and grandsons will also stand by the company.
Based on a switched identity, in circumstances that are found in real life as well as fiction, this drama tells the story of two soldiers fighting together in World War I. Karl (Joachim Latsch) and Richard (Hans-Use Bauer) become close friends while serving time in a German POW camp. One day Karl manages a successful escape and goes to Richard's home where he seeks refuge posing as Richard. But Richard's wife Anna (Kathrin Waligura) has never given up hope that her husband is still alive -- a possibility that would shatter Karl's proposed new life. In fact, Richard did not die in the POW camp. This film shared the Grand Prix award at the 1985 Berlin Film Festival.
