Lasse and Maja are two kids who run a detective bureau. As the film starts, kids find a chest made by the composer Alexander von Broms in the local-church crypt, with a cryptic message attached to it. The chest appears to solve the church's financial problems; it's in urgent need of restoration. But when von Broms' relatives appear and claim that the chest is theirs, a conflict emerges. A few hours later, the chest gets stolen and Lasse and Maja tries to find it. The adventure begins in the city of Valleby with its surreal surroundings. There are puzzles to be solved and mysteries to be revealed and the whole family can join in.

Sleepy Valley gets ready for cafe owners Dino and Panini Sara Bernard's wedding, and our beloved junior detectives Lasse and Maja stand ready to ensure that nothing goes wrong. But when the wedding couple's respective relatives arrive, they show themselves to belong to rival Mafia families. When the Panini family's crown jewels suddenly disappear, Lasse and Maja soon realize who the main suspects are.

It's late summer in the small town of Valleby, but the calm is disrupted by bad news. The police station is under threat to be closed, which neither Lasse, Maja nor the chief of police wants. They must find a way to solve the situation.
