Biriba is a lowly but talented drug dealer whose future is disrupted by the legalization of weed in Brazil. His best friend Salim wants him to become a bigger player in their current criminal enterprise, but his client Vini presents the possibility of becoming a legitimate businessman.

With the papers signed, Biriba and Vini start going through the pains of building a startup. Vini enlists their new financial manager Digao to help find a supplier before it’s too late, while Salim attempts to keep Biriba entrenched in the illicit drug market.

Biriba and Vini are officially in business but they still have a lot to learn about the product Joselo is supplying them. Salim shares big news with Biriba in a step towards reconciliation, while Piolho hatches a scheme to move up the ranks at the smoke hole.

Salim's marijuana sales are dwindling, and he can't meet the demands for higher payoffs from the local police. Biriba is confronted by a city inspector intent on putting him and Vini out of business unless they pay their fair share.

Mary Jane's Emporium begins to lose customers when a competitor opens a small dispensary next door and the gang hires a firm to help promote the company's image despite Biriba's reluctance.
