One of the DivEdCo's films that best depicts the history and evolution of another genre of popular music from the coasts and of African origin: the plena. It presents sequences of interpreters of those rhythms in Ponce, in the dances of the coastal areas, and the fusion of popular and refined genres in presentations by Ballets de San Juan of the ballet-plena by Amaury Veray, "Cuando las mujeres" ("When the Women").
