With Escobar down, a new cartel is up: The Pacific Cartel in Colombia, led by Óscar Cadena, so Óscar (the teacher) and Martín (the student) make a pact of friendship and business.
Martín refuses to take part in this war and decides to go to Miami with Sofía and his children, unaware that Miami is no longer a safe place.
He continues his illegal activities, meanwhile watching enemies kill his old friends.
As increasing numbers of his business partners and brothers die or get caught, Martin is forced to run to Mexico, looking for protection.
He realizes too late that, in this business, you can never win.
El Cartel de los Sapos (English title: The Cartel of Snitches) or El Cartel is a Colombian television series that first aired on June 4, 2008 on the Colombian network Caracol TV.
El Cartel stars Manolo Cardona, Karen Martínez, Diego Cadavid, and Robinson Díaz and is based on the 2008 novel by the same name by Andrés López López, alias Florecita ("Little Flower"), a former drug dealer who, while in prison, wrote the fictionalized account of his experiences in the Cali Cartel and of what happened within the Norte del Valle Cartel.
In the TV series, which Lopez also wrote, the characters and locations from the book were changed.
Two friends enter the illegal drugs business, thinking it is the fastest way to become rich.
The illegal drug trafficking world seems attractive to all these middle-class people, who overlook the associated dangers and legal problems.
