Marco trains Johan and Rasmus for the infiltration of the drug ring. But the preparations are hampered by language conflicts and a stomach that is hypersensitive to milk protein. Once they come face to face with the ring leader, Johan goes all out in his new role as an undercover cop while Rasmus thinks a friendly email is the way to success.

Before the meeting with Moskito, the guys decide to steal weapons from a hashish dealer. However, Johan risks the entire operation when he tries to impress an old colleague on his own initiative. Meanwhile, everything starts to smell burnt for the substandard undercover gang when the owner of their safehouse suspects that the house is being used for an illegal pornographic film shoot.

After an unpleasant fryer incident, Rasmus and his nervous stomach want to duck out of the meeting with Moskito, but Marco persuades him to hang in anyway. Once there, the whole operation goes awry and everything is brought to a head when the undercover mission turns out to be something different than what Johan and Rasmus thought.
