I am looking for the name and possibly a copy of a movie I saw in Europe in 1985.  It starts with the 10th wedding anniversary of a couple.  That night the wife and daughter are kidnapped, and presumed dead after a car accident.  Many years later the father meets a young woman in Italy looks and walks like his presumed dead wife.  She turns out to be his daughter.  He later finds out the kidnapper was his business partner who wanted to destroy him and the story develops from there.  Please help me find the title of this movie, I've been searching for 16 years.
