This documentary rediscovers the history of the 20th century through the narrations of investigative journalist and historian Rogelio Garcia Lupo. He cofounded news agency Prensa Latina together with Gabriel Garcia Marquez, Rodolfo Walsh and Jorge Masetti, as well as the CGT workers’ weekly newspaper. Using a chinese box structure, we access García Lupo’s archive, while he classifies it, at age 82, before donating everything to the National Library, for future investigators to consult.
