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.

Deep inside the mountain of Dovre, something gigantic awakens after being trapped for a thousand years. Destroying everything in its path, the creature is fast approaching the capital of Norway. But how do you stop something you thought only existed in Norwegian folklore?
