Boyden and Worrell arrest a man dealing drugs to schoolchildren, but soon discover that he is the son of a key witness to a case which Beech is desperately trying to close. Beech warns Boyden off as he is desperate to nail long-term enemy Jack Masters , but Boyden has other ideas. After managing to get him off a dealing charge, the suspect then assaults one of Masters' informants, and again Beech manages to get him off; little does he know that he is using the case to clear his name completely.
