Late on a hot summer night in 1965, Charlie Bucktin, a precocious and bookish boy of thirteen, is startled by an urgent knock on the window of his sleep-out. His visitor is Jasper Jones, an outcast in the regional mining town of Corrigan. Rebellious, mixed-race and solitary, Jasper is a distant figure of danger and intrigue for Charlie. So when Jasper begs for his help, Charlie eagerly steals into the night by his side, terribly afraid but desperate to impress. Jasper takes him to his secret glade in the bush, and it's here that Charlie bears witness to Jasper's horrible discovery. With his secret like a brick in his belly, Charlie is pushed and pulled by a town closing in on itself in fear and suspicion as he locks horns with his tempestuous mother; falls nervously in love and battles to keep a lid on his zealous best friend, Jeffrey Lu.
