In Norse mythology, the definition of the end of the world. Ragnarok begins with natural disasters and culminates in the great battle between the gods and the giants.
Returning to his family’s hometown, awkward teenager Magne discovers his strange new powers. Still, the hamlet's natural beauty cloaks dark secrets.
Teen Magne, his mother, and his younger brother Laurits return to the Norwegian town of Edda after many years of absence. Their father died in Edda when they were children and they moved away. As they drive into Edda their car gets stuck behind an old man on an electric vehicle in the middle of the road, who comes to a halt trying to turn right. Magne gets out of the car to help, and is approached by the old man's wife. She tells Magne he is a good boy and looks up at him intensely before touching his forehead. A change flickers through his eyes. The two brothers begin attending the local high school and awkward Magne becomes friends with green advocate Isolde. Isolde later dies when she appears to paraglide into power lines. That night, a distraught Magne holds his father's sledge hammer as lightning fills the sky. He throws the hammer and it disappears into the clouds.
- At the end of the episode, Magne hurls his father's sledgehammer (deliberately modeled to be reminiscent of most popular depictions of Mjölnir) over 1,500 kilometers. The second episode reveals it was embedded in the windshield of Vidar's car. But why didn't the hammer return to him, as it is famous for doing? Because that was a property of Mjölnir, made by the finest dwarven smiths and so powerful Thor himself needed a special gauntlet to hold it. It wasn't one of Thor's own powers, so Thor throwing any old non-Mjölnir hammer wouldn't get the benefit of it always returning to his hand, "no matter how far or fast he hurled it."
- The Alleged Car: Turid's car has shades of this, with the engine having problems to start and the window crank breaking off.
- And Show It to You: Vidar kills a reindeer and rips its heart out. Then he takes the heart to a cliff over the fjord and bites into it.
- Big Brother Bully: Inverted with Magne's younger brother Laurits. When Magne asks him to proof-read something he wrote, Laurits changes the entire text, making Magne look stupid. Later, when Magne is hiking with Isolde, Laurits texts him saying that something happened to their mother even though she is perfectly fine. Magne hurries back home and Isolde has a deadly accident with her paraglider.
- Character Death: Isolde is flying too low with her paraglider and she ends up flying into a power line and falls several meters to the ground.

- The Glasses Gotta Go: Played with. Magne's mother thinks that he doesn't want to wear his glasses anymore because he is ashamed, but Magne really doesn't need them anymore after getting his powers.

- Gray Rain of Depression: It starts to rain heavily when Magne walks home after Isolde dies, fueled by his new powers.
