Who wouldn't want to have a superhero dad admired by the whole city? They've even built him a statue in the middle of the square! Who wouldn't want to be his successor? The little Hedvig has affirmative answers to both questions. But it doesn't look like she's going to take up the family scepter of the city's masked protector Super Lion. At school, she is an outsider and has only one friend, with whom she plays computer games all day. One day her whole life is turned upside down after she causes an unfortunate accident. Hedwig has to convince her father that she is the right candidate to become a superhero. Her grandmother, who is currently living in a retirement home but likes to reminisce about her career as a superhero, helps her in her difficult battle with her cousin Adrian. In addition to action and humor, the Norwegian animated film also offers an answer to the question of what it means to be cool.
