Nelson, a young native of Misiones, travels to Buenos Aires to take a fight rooster to his brother. When not finding it he undertakes a search by the town that will take him to tie itself with the head of a band of pirates of the asphalt.
The incident suffered by Loquillo modifies the plans of the rest of the band, which must act urgently. Nelson is in the eye of the storm and Chelo's distrust reaches a limit.
Nelson takes hold in the band, but tensions emerge that force him to take a position. In turn, Chelo is not willing to lose territory and harden his movements.
Nelson and Esculapio travel together to meet rooster fights, but suffer a series of difficulties along the way that, with the cunning of Esculapio and Nelson's mischievousness, try to overcome, with an outcome that will surprise.
