DI Baynham and the Christmas Street team are joined by new recruit Pc Judy Byrd.

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.

New Recruit Pc Judy Byrd has the thankless task of stepping into Terry's shoes, when she's paired with his former partner Pete. To make matters worse, the whole team's still in mourning and she doesn't know how to deal with their grief. Meanwhile, a seemingly drugs-related death at the hands of an angry mob, on a supposedly crime-free estate, baffles Tony and Ray, whose investigations are also hampered by a pair of hapless street robbers intent on pulling a major job in the city centre.

As DI Tony Baynham prepares to tie the knot with Maggie, he thinks all he's got to worry about is being late – but he hasn't taken into account the flooded reception, an old mate who wants to kill himself or the return of his old flame Lucy!

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.

Looks like the game's up for DS Ray Pickering. Station boss Chief Inspector Barnard has found out that Ray's got to know his young daughter in the biblical sense. Loose cannon Pc Steve Jackson, having been booted out of the Armed Response Unit, decides he wants to start a family. How will his poor wife Debs react to such an unusually mature proposition?

A 15-year-old boy is reported missing, and Colin and Nick have to sort out a hen party.

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…
