Batimam and Robim.

Batimam and Robim are two close friends. Their real names are Léo and Mário, but they've got those nicknames after dressing up for mardi-gras as Batman and Robin. To get some money, they decide to rob a small supermarket, but they meet some reaction and Mário gets shot by the owner, who is killed by Léo. They run away and find solace in an abandoned house. Léo decides to go out to try to get some help for his friend, whose leg was wounded, but to no avail. When he returns, the two start an argument.
