S15·E57 Integrity: Part II

With DS Vickers blackmailing him over his use of cannabis, Klein is more determined than ever to bring the corrupt officer down. Brownlow asks Worrell to join the case, but she accuses him of going after her skin colour, rather than her ability to do the job, and turns it down; instead, the role goes to Rickman. She is tasked with going undercover as Sally Holland, with her cover being an ex-girlfriend of Anil Indrani in order to lure Vickers into planting drugs on Indrani. Vickers calls on Smith to help him with an unauthorised OBBO, and when he recognises Rickman, he blows her cover. Klein confronts Vickers as a last resort, but he is devastated to discover that Vickers has arranged for Area Drugs to bust Indrani, and he is arrested along with Klein's girlfriend Pam. Klein is furious to discover that it was Smith who blew their undercover op, and presents him with all the evidence he has on Vickers in an attempt to open his eyes to what his friend is really like.
