Mathias is twenty-seven and is starting to think about whether it might be time to grow up. But the guys he lives with have COMPLETELY different plans.

The boys are looking forward like little hell to "Dagsfylla" at Sander Lund. They have rented limmo and bought triple-magnum champagne. But when they arrive at the party, they get an unpleasant surprise. Sander Lund has changed the theme of the party. The theme is not "Dagsfylla" anymore, now it is called "Classy Lunch".

Herman needs cash and goes to unorthodox methods. Mathias becomes suspicious of a colleague of Frida.

Herman, Leo and Jens protrude vertically in an attempt to spy on neighboring men. In order to correct the impression, they follow them on a feminist event hoping to check them up.

Herman gets an opportunity to develop his Snus app in exchange for 50 thousand he does not have. Leo falls in love with a girl with creepy motives.

The boys are insanely small and have to hide in the apartment in order to get rid of the dwellings. How should they get food without being discovered?

There is still a break between Frida and Mathias, and Mathias is tired. So to try and win her back, the guys have to go on a demanding expedition - to Greenland.

A heated discussion about which method is best for getting rid of cum causes Mathias to think - maybe he will find some friends with more intellectual interests?

Herman has succeeded with the Snusbrothers app, and has his own office with many employees. At least, that's what he tries to trick his father into believing.

The boys discover a shocking secret about Jens. They decide to get to the bottom of it, but the bottom is somewhere they never thought they had to go.
