Tommy is finding the transition to his job with the Unit a difficult one. The team follows every move made by drug dealer Xavier, hoping he will lead them to someone bigger. But when he meets with a rival dealer things go very wrong.
Whilst shadowing drugs dealer Xavier the team discovers that he is up against a rival gang led by a boy called Fitz. They are using adapted guns which are lethally unstable and claim a casualty. D.I. Gemmill tells Ash that somebody is flooding the capital with them and must be stopped. At the same time Tommy is concerned that Fitz may be involving young Cal, guardian of his little brother and sister whilst their mother is in hospital but Cartwright opposes the team showing its hand to Xavier as it would destroy the link to his boss. Cal makes his own luck and the team rounds up the gun peddlers but Roach still remains at large.—don @ minifie-1
