10 long years have passed since the first film about the super duo, and things are not so great anymore. Tina married an 89-year-old, who just refuses to die so that she can finally get the inheritance. Bettina, on the other hand, tries to keep her spirits up in a rotten marriage where all she does is look after the ungrateful man's children. And almost even worse - no one does video blogging anymore, and after a heated argument, the girls have lost contact with each other. Life sucks. But when Tina goes crazy at the VIXEN awards, and the recording from there goes viral, Tina & Bettina are suddenly on everyone's lips again.

In Western Europe, on the west side of Scandinavia, on the west side of Oslo, is the greatest place on earth - Smestad. This is where Tina and Bettina lives, the most popular teen girls in high school. With a teen life filled with blogging, boys and parties, everything is great for the girls, right up until they stand before a terrible problem - immigration.
