Simon 'Ghost' Riley was a 32-year-old elite British special forces soldier, member of Task Force 141.

A few years ago, in the war zone where he was now on a mission, he had saved a girl… his first and only love.

She disappeared, her body never found and no trace of her ever again.

Every time Ghost returned to that place a sense of emptiness enveloped him, and he looked at the photo of him and that girl he always kept in his helmet.
