Outwardly a respectable businessman Jamie Caine is a murderous, large-scale drugs dealer who kills a boy but is released after the key witness is intimidated into withdrawing his statement. Against orders from her boss Helen calls in Jack and his colleagues to bring Caine down and they discover that Bates, Caine's henchman, has organized a major drug deal whilst Caine was in custody - the receipt of 2C9,an hallucinogen aimed at young kids. Jack and his team raid Caine's factory but find no evidence and see that they must catch him red-handed doing the deal. Charlie persuades Caine's 17-year old girlfriend Robin, whom he used to know, to act as informant but Caine kills her, making it seem that Charlie, who has gone undercover to rescue her, is the culprit. The team must hope that the information supplied by Robin will lead to catching Caine in the act, as well as exposing the authority figure and drug user who has allowed Caine to remain at large.
