In 1980, a Cuban refugee named Tony Montana arrives in Miami, Florida, during the Mariel boatlift, where he is sent to a refugee camp. Montana soon finds himself involved in the drug trade, as he and his friend Manny Ribera perform a hit for Frank Lopez, a wealthy drug lord. Impressed with their work, Lopez brings Tony into his organization, setting him on a path of ambition and greed. Tony's ruthlessness and drive see him rising quickly through the ranks, leading to tensions both within the organization and with rival gangs.

As Tony climbs the criminal ladder, he becomes obsessed with power and wealth. His relationship with his boss begins to deteriorate due to his growing ambition and impulsive behavior. After ensuring a deal with a Colombian drug dealer goes smoothly, Tony attracts the attention of Lopez's girlfriend, Elvira, and the two start an ill-fated relationship. With his eyes set on Lopez's position, Tony maneuvers himself into a place of power, but this ascent sows the seeds of discord among those he knows, including his family. Meanwhile, his increasing reliance on cocaine and his unpredictable nature threaten to undermine his empire.
