A child is snatched for ransom from a school. However, the wrong child was taken, the abductors have a royal child. Following information from an informer, as to who the child really is, a people trafficker purchases the child. 

This escalation now involves Unit T, a specialist unit set up to combat people trafficking, run by Lieutenant Karen Harris CGC. The trafficker organisation known as the 'Circle' has had enough of this girls interference and decides she must be eliminated. Now Karen becomes the hunted, not the hunter in a fight not only her own life, but her units survival.
