As he and PC Quinnan investigate a burglar alarm, PC Eddie Santini sees Jessica Orton meeting covertly with Ferguson. Making excuses, Santini borrows the panda car and races to the Ortons' club where he confronts Jessica. As she storms off, there is a huge explosion. Santini is shocked when one of the officers assigned by AMIP to investigate the explosion is his old nemesis, DS Rosie Fox. Fox is suspiscious of Santini's involvement, but her colleagues put it down to the animosity between them. As Santini returns to his flat, where his lover PC Vicky Hagen is waiting, he is kidnapped by Ferguson who assigns him the task of picking up a consignment of drugs from Amsterdam.

Jessica Orton is brought in for questioning, but is released without charge. When she returns home, PC Santini is waiting for her, desperate to know if she grassed him up. They fight, and Santini hits Jessica, knocking her down the stairs and killing her. Realising her house is being watched, he escapes out the back. Vicki Hagen finds a set of keys under Santini's bed which she brings to the station to return to him.

Santini tries to convince his lover, Jess Orton, to set him up with some drug dealers – he wants out of Sun Hill, and DS Timpney, his friend in Area Drugs, has promised him a place in the squad if Santini can get him evidence on them. However, before he has the chance, the Ortons' club is firebombed, and Santini is shocked when one of the officers assigned by AMIP to investigate the explosion is his old nemesis, DS Rosie Fox. Fox is convinced that Santini is linked to the events in question, but her AMIP DCI, Richard Pallister, believes otherwise. When Santini manages to locate Jess Orton, he persuades her to make a false confession to bombing the club in order to gain the trust of the suspected drug dealers.
