Medical nurse Stephanie Blake (Michelle Bonnard) is thrown down the stairs at her flat by a mystery assailant, evidence of a stalker named 'Giovanni' comes to light. It appears that for the past two years, the stalker has been sending Stephanie e-mails and telephone calls claiming to know every last detail about her. Lucas Dutton, a man whom she met a local bar, claims to know nothing about the stalking – but when he is revealed to be a bit of a dark horse, Brooks & Devlin suspect there is more to him than meets the eye.

When Russell Lowry (Rocky Marshall), a conceited ladies man, is revealed to have contacted Stephanie through an animal charity that Stephanie worked for, suspicion falls on his involvement in the case. However, at the time the e-mails and phone calls started, Lowry was in prison for a GBH charge. When no physical evidence is found at the scene of Stephanie's fall, Brooks & Devlin suspect that Blake threw herself down the stars as a cry for help, as the police involved with her stalking claim failed to help her. In interview, Ronnie shows her a picture of Lowry and asks if he was the man who pushed her – and unable to remember, he believes she did throw herself down the stairs – but she claims that if she is not given help she will end up dead.

Upon her release, she returns to her flat – but within hours is found dead, slashed across the neck. The only clue is a 999 phone call, made by Blake moments before her death, claiming 'it's him, it's him, the man from the photo', indicated that Lowry was her killer. Ronnie decides to review the evidence – and when the landlady of the building reveals she buzzed someone in around the time of Stephanie's fall, he believes that she was, in fact, pushed by Lowry as well. When the case comes to court, James comes up against Evelyn Wyndham ( Anna Chancellor ). However, Ronnie's review of the evidence comes under scrutiny from Matt – and in order to secure a conviction against Lowry, James must discredit Matt's view.
