Movies like Cinema, Aspirins and Vultures

In 1942, the lonely German Johann travels through the arid roads in the country of the Northeast of Brazil in his truck selling Aspirin in small villages, using advertisement movies to promote the medicine. He meets the drifter Ranulpho, who intends to go to Rio de Janeiro seeking a better life, and gives a ride to the man. While traveling together, they develop a close friendship, but on 31 August 1942, Brazil declares war to Germany and Johann has to decide if he should return to his home country and fight in the war, or stay in Brazil in a concentration camp; but the option of moving to Amazonas with the migrants of the drought seems to be feasible.
