Rufino sells a bag of cocaine for Ochoa, a corrupt cop who has Rufino's district in his power and is also the lover of Rufino's adoptive mother. He decides to use the money to flee the city with his girlfriend and her baby. Ochoa sets off after them. Just as Rufino seems able to escape, he finds out that his real father is still alive.
