The Pite boy Bosse accompanies his father to the Boden trot and becomes skilled at gaming and betting at an early age. One day he decides to go to Stockholm with his best friend Josh to become a professional player. They embark on the hunt for the big money, terrified of being forced to return to Piteå without a penny in their pocket. At Solvalla, Bosse meets the trotting trainer Gabriella, who gives him a valuable tip. Together with their friend Lars-Erik, they start betting on Oddset. It is now that Bosse discovers that something is very wrong in sports Sweden.

Bosse has been told that there are match-fixing. Now he and his friends are swept into a shady world of great risks and shady bookmakers. When he takes care of his father's gaming kiosk while his parents go on vacation, he finds a loophole in the state-run Tipstjänst's routines and gets big money to bet on matches. Then come the three games that will give them a million-dollar win. At Tipstjänst, inspector Therese begins to suspect something is wrong.

Bosse, Josh and Lars-Erik have six days to get the money they borrowed from Tipstjänst. Otherwise, the bubble will burst. Now they have to set up a layup match themselves. Therese at Tipstjänst contacts Bosse's father Gunnar about the delayed payments. Has he noticed that someone plays extra much at certain matches? Bosse's conscience begins to gnaw. At the same time, he chooses to get engaged.

An unlikely chance to play arises for Bosse, Josh and Lars-Erik. Three games with the team Frölunda in the same round. But Bosse wants to know if the players in the team intend to fold. A dangerous game starts where the talk goes and the stakes are breathtaking. In the midst of the turbulence, Bosse and Ylva are planning a wedding.

The scandal is a fact when Expressen reveals that a gambling mafia cheated Tipstjänst. But neither Tipstjänst nor Sport-Sverige want to acknowledge that matches have been fixed. With the help of Therese, Expressen's journalist has brought up the weathering on Bosse. And more dark clouds begin to tower in Bosse's sky.

It is drawing up to a defamation trial against Expressen's editor-in-chief. Bosse has been called as a witness and both Expressen and the prosecutor want to make sure that they have Bosse on their side. How will he get through the trial without going there himself? At the same time, Bosse experiences a dramatic change in his life.
