Synopsis: Dear Sirs sheds light on the little-known suffragist movement in Colombia. Set in 1954, the film follows Esmeralda Arboleda, a fiercely intelligent leader, who ignites a revolution in a society steeped in patriarchal traditions, culminating in a bitter and decisive debate. A group of women embark on a historic struggle to bring women's suffrage to the National Constituent Assembly. With bold marches, radio appearances, and a brilliant media strategy that puts them in the spotlight, they achieve their goal, but the real challenge begins in the debate, where they face fierce opposition. Esmeralda Arboleda must endure personal attacks from the assembly members, and just as she is about to speak, she receives a heartbreaking call: her son has been in a serious accident. She is torn between her duty as a mother and her commitment to the cause, with an unfavorable outcome. Although it seems that all is lost, her perseverance leads to a historic victory when women's suffrage is finally approved, marking a turning point in the history of Colombia.
