In early 20th-century Britain, the growing suffragette movement forever changes the life of working wife and mother Maud Watts (Carey Mulligan). Galvanized by political activist Emmeline Pankhurst (Meryl Streep), Watts joins a diverse group of women who fight for equality and the right to vote. Faced with increasing police action, Maud and her dedicated suffragettes must play a dangerous game of cat-and-mouse, risking their jobs, homes, family and lives for a just cause.
