Having proved his grandfather Fergus? innocence, Danny Watts and his friend Elena have now been recruited by the British government for a dangerous assignment. Elena must impersonate a would-be suicide bomber to win the confidence of Black Star, the master computer hacker who is behind the rash of teenage bombings that have swept the globe.

When Black Star sends Elena to New York, Danny and Fergus come along to keep an eye on her. But Fergus knows that once this mission is over, the government will have them all eliminated. As Elena begins to fall under Black Star's spell, it will take all of Danny's survival training to find a way out.
