In 2007, 11-year-old Rhys Jones is inexplicably shot dead walking home from football practice. When newly-promoted Superintendent Dave 'Ned' Kelly, leading the murder inquiry, discovers that Rhys' older brother Owen was in a gang, he suspects that Rhys was innocently, inadvertently caught up in turf warfare. Meanwhile, teenager Sean Mercer hides a gun and an anonymous caller names Mercer and two fellow gang members as the culprits. However, Ned is unable to gather sufficient evidence to charge them.
