Determined to celebrate in style, at her 25th birthday bash WPc Sue Chappell ends up in the arms of Det Sgt Ray Pickering and they're not the only ones letting their hair down! Sue's had a day to remember after facing a gun-toting robber but when she has second thoughts about the job, hotheaded cop Steve shows an unexpected side to his personality… Pc Richard Law is visited by a deranged young man looking for his brother. Sue's birthday celebrations are marred by an interview that leaves her shaken.

Out shopping on his day off with his girlfriend Alison, Terry plays the hero when he nabs a shoplifter. But back on the beat, though, he bumps into an old school pal and realises being a boy in blue has its downside…

A second body has been discovered and a new incident room is set up. To Ray's disappointment, DS McCormack is recalled to the case and the inquiry's progress is hampered by the loss of some important pathology reports. Meanwhile, Steve and Colin are on patrol when they see a chance to catch a recently released prisoner.

Terry's gone and those he's left behind have all been affected in a big way. His mum is beside herself with grief and his partner on the job, Pete Redfern, doesn't know what to do with himself. Hot-headed Steve Jackson however has decided the best thing to do is join the Armed Response Team… Tony and Ray chase a vigilante who hunts down drug dealers.

CID prepares surveillance on Les Glover, a club owner and drugs dealer who is gathering cash for a big deal. Meanwhile, the uniform team lays bets on the identity and gender of Colin's new partner.

Pc Pete Redfern is not a happy bobby. Still not over the death of his young protégé Terry, he's now looking after another fresh-faced probationer, the very irritating Judy Byrd.

A call comes in to Christmas Street, warning that an officer will die by 5.00pm that day. Not much notice is taken until it is discovered that a character named David Crane – who has been in prison for stabbing Pete Redfern's partner Mance – is on his way up north.

A man is brought in who claims to know the identity of Pc Terry Sydenham's murderer. A car left by Nick as a decoy is stripped by thieves.

Terry's Sydenham's death has cast a shadow over the Christmas Street team, so they're relieved when his killer is finally captured – but will Sgt Mackey be?

Connor Rice has been arrested and charged with the murder of Pc Terry Sydenham. However, with no hard evidence available there's a chance the thoroughly nasty drugs dealer could walk free. Not something Terry's mentor Pc Pete Redfern wants as he prepares to retire…

Gagan continues to interrogate Connor Rice; Steve and Sue are caught in a pursuit through the city centre; and Tony receives bad news.
