The testimonies of some artists on mural painting in Puerto Rico, as well as art historians and curators, offer multiple perspectives of the mural paintings in different geographical areas of the island.

Using as a thread the transfer of the work Portrait of Luis Muñoz Marín from the Museum of Art of Puerto Rico to the National Portrait Gallery of the Smithsonian Institute, the documentary explores the work and the creative process of the artist Francisco Rodón and the series of portraits known as the Personajes de Rodón. The testimony of the artist is complemented by comments of history specialists and art critics Hiromi Shiba, Marimar Benítez, and Taína Caragol.
