Bert's class will collect money for a 9th grade school trip to London.

Åke proposes selling nuclear weapons to the Sami people and use them against the Swedish government, which he believes oppresses them.

Feeling down, Bert goes to church, where he meets a girl who tells him she had the same problems when she was fourteen.

Åke states that he and Emilia only talk over a "child born on Christmas" and hold hands, but Bert doesn't believe that.

Later during the same month, Bert, Åke and Lill-Erik sleep overnight at Ekeboskogen, where according to rumors a UFO is said to have been seen.
