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.

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.
