What happened in How to Sell Drugs Online (Fast) Season 4?
How to Sell Drugs Online (Fast) Season 4 takes place four years after the events of Season 3, where Moritz is sentenced to prison for selling drugs online through the MyDrugs website. After getting released on parole, he joins the start-up venture BonusLife, co-founded by his friends Lenny and Dan.
Fueled by bitterness and jealousy, Moritz plans to take over the company by becoming its major shareholder. As per his contract, he has a 2 percent stake in BonusLife, and purchasing an additional 49% shares (secretly) will give him 51 percent stakes in the company. But he is unaware that the business is on the verge of claiming bankruptcy.
Moritz arranges the funds by taking a loan of €1 million from Ersan's boss, Behzat Aygün, owner of Brofrost Frozen Foods. However, he is unaware that Behzat is a criminal drug lord who uses Brofrost as a front business to carry out his illegal drug trafficking.
The police are alerted about Brofrost's illegal activities after spyware Moritz had programmed to help them keep tabs on the criminal gangs and their operations. It was part of the deal he made with the police to secure his early release from prison. After Behzat's illegal operations come under the scanner, he begins suspecting his own drug dealers of being a mole and kills them off one by one.

However, Moritz explains to him that the mole is a spyware, and not an actual person. To fix the issue, Behzat forces Moritz, at gunpoint, to develop an encrypted software that will protect his devices from the spyware and keep his gang's interactions safe from the prying eyes of the police.
Meanwhile, Moritz's ex-girlfriend, Lisa Novak, learns about the string of murders in her hometown and tracks them down to Behzat. She survives a murder attempt by the criminal drug lord that claims the life of her boss, Elif.
In episode 5 of How to Sell Drugs Online (Fast) Season 4, the police raid the Brofrost headquarters, effectively shutting it down forever. Behzat survives the raid and takes Moritz, Lenny, and Dan hostage to get them to fix the servers so that he can operate his business online.
While escaping together, Moritz decides to surrender himself to Behzat in exchange for Lenny's safety. Lenny comes to believe that his best friend died at the hands of the crime boss, but in reality, Moritz survives a standoff between himself, Behzat, and his goons. He fakes his own death and goes to live on an oil rig, far away from his friends so that they can stop getting dragged into his mess.
