Watch Full Movie Online. Although too long by half, this documentary is subtitled "A Trip Through Lotti's Life" and that is essentially what it is. Although done in a style that keeps you guessing what is true and what isn't about her life -- everything from her Aryan lover and her stay in a concentration camp while he is killed for their forbidden love -- it is a fascinating look at this remarkable woman through the eyes and viewfinder of Rosa Von Prauheim.
