A young woman murdered in a run-down Manhattan hotel.
A father publicly beheaded in the blistering sun of Saudi Arabia.
A man's eyes stolen from his living body as he leaves a secret Syrian research laboratory.
Smoldering human remains on a mountainside in the Hindu Kush.
A plot to commit an appalling crime against humanity.
One thread that binds them all.
One man to take the journey.
Pilgrim.
