The film tells the life story of Louise Otto Peters, who in the middle of the XIX century in Germany for the first time raised a voice of protest against the unfair treatment of women and their labor. She created the first "women's newspaper" in Germany. The daughter of a famous lawyer, Louise could have easily arranged her life by marrying the wealthy Baron Rodern. But she chose a different purpose in life - to fight for equal rights for women. Through her articles and public speeches, she won the authority and respect of ordinary people.
