Bert dreams of how he and Jenny make out in the park, but the fantasy quickly collapses. She is the sister of Bert's worst enemy, Klimpen, who is always around when Bert tries to talk to Jenny. What is he going to do? Åke comes up with a studied plan.

Bert wakes up with a big pimple on his nose and hides in his hoodie all day. On the way home from school, Bert encounters a new girl, Shirin, who immediately starts writing to him on Instagram. At the same time, Åke realizes that he suffers from an electrical allergy.

When Bert roasts the French teacher, he arouses the curiosity of the cool leader type Alicia. After school, he accompanies her tough girl gang to the mall where they talk shit about everything and everyone. Bert is happy, but Thora is worried about his new relationship.

Bert falls head over heels for Elin who is behind the counter at the town's new café, Cup & Joe. Unfortunately, he has to go there with his lying cousin Lydia because his friends prefer to hang out at the old coffee shop Bikupan.

Bert learns that Lill-Erik is exchanging emails with a Finnish girl named Minna. Bert wants to help Lill-Erik to enchant Minna, but when Lill-Erik seems reluctant, Bert takes matters into his own hands. At the same time, Åke and Thora end up in a bet with high stakes.

There is a swimming lesson and Bert looks forward to spying on the girls in swimwear, but when Thora explains that the girls are spying on the boys at least as much, Bert panics. He finds a miracle diet on YouTube that will give you a super body in three days.

The gang continues to hang out with Vanessa and everyone thinks it's cool that she streams computer games in her spare time. However, Bert has a problem. He thinks he's in love again, but he cannot be in love with someone who is part of the gang!

Klimpen has suddenly become a girl's magnet and Åke explains that it's all about Klimpen's new shirt. It's the same shirt that gangster rapper Érnst is wearing in his latest video. Bert also wants the magic sweater, but it turns out to be expensive.
