10-year-old Håkan is a huge fan of movie star Jens Raptor’s action films. Fueled by the boy’s vivid imagination, even an ordinary trip to the store with his best friend Beiron turns into an apocalyptic zombie hunt. However, Håkan finds himself in a new situation when Beiron says he’s tired of watching the same old action movies over and over again. He’s more interested in Tinder, where he dreams of finding a girlfriend. Håkan is convinced he’ll lose his best friend unless Jens Raptor makes a comeback on the big screen. Meanwhile, Håkan’s parents have their hands full preparing for the wedding of a couple they’re friends with. At Håkan’s suggestion, Jens Raptor’s mansion is chosen as the venue. But the wedding is in jeopardy due to a series of inexplicable pranks, and Stefan, who is in charge of security, asks Håkan to track down the mysterious saboteur. In return, the boy would finally be able to speak to his idol to persuade him to star in a new movie. The quick-witted Håkan steps into the role of secret agent 003 and immediately begins gathering clues about the culprit.
