Bar entertainer Zara is a discontented alcoholic who is pursued by many men but lives with novelist Carl Salter. One day, Tony shows up on Salter's estate claiming that Zara is actually Maria, the wife of his close friend Bruno, claiming that her memory was destroyed during World War I. Zara doesn't remember but leaves with Tony to Salter's dismay. Bruno, now an officer in the Italian Army, tries to coax Maria's memory back on his large estate. No one is really sure if Zara is Maria, and when Salter shows up with a mental case from Trieste that he claims is the real Maria, everyone on Bruno's estate is desperately searching for the truth.
