Detective Inspector Greg Bowker must travel to the town of his childhood to investigate the murder of an elderly man, one who happens to be Greg's old school teacher.

His visit reignites boyhood memories of he and his younger brother discovering a blood-covered body on the slopes of a stony, scrubby hill known to those in the area as the Granite.

As the investigation evolves, Bowker and his partner become convinced that the old teacher's demise is somehow linked to the death of the man on the Granite almost four decades prior.

But are their instincts correct?
