The Scarlett Sapphire

Scarlett, a distraught mother, is turned assassin when her son is kidnapped by an enigmatic organisation who wish to control her for a unique talent she possesses. For years she has walked a violent and bloody path in search of her son, but now the path ends as she is brought face to face with the man responsible. In a small bar, at the end of the world, Scarlett's mysterious assailants play their hand in a bid to manipulate her into completing one last job, but find they have grossly underestimated the lengths this mother will go.
