Oakdale's Mystery Team was once a spunky band of kid detectives dedicated to solving child-sized mysteries: who put their finger in the pie, or who stole a tricycle. The town loved them for it. Now the Team is about to graduate from high school and move in to the real world, but they're still storming the playground to bust little kids. Needless to say, the town of Oakdale is sick of it. Each member of the Team has a supposed specialty: Jason, the "Master of Disguise;" Charlie, the "Strongest Kid in Town;" and Duncan, the "Boy Genius."

But those skills may not be enough when one day a neighborhood girl asks the team to find out who killed her parents. The Team is taken for the first time into Oakdale's dark underbelly. A violent cartel of drug lords and strippers will threaten their lives, strain their friendships, and put their team slogan "NO CASE TOO HARD, NO CASE TOO TOUGH" to the test.
