When two fishermen find the body of a local farmer in the river, Detective Inspector Mike Shepherd is sent to the small rural town of Brokenwood to investigate the death. Is this the suicide of a man guilty of his own wife’s murder or is he the victim of foul play? As Mike uncovers a family’s tragedies and secrets, he also learns that Brokenwood is a place where shadows lurk just beneath the surface.

With Brokenwood touted for its burgeoning merlot, the annual wine show is a major event. Having bought a 10-acre block with maturing grapes, no one is looking forward to it more than DI Mike Shepherd. But when a guest judge and wine critic is found dead, drowned inside a fermenting vat, the show takes second place to the murder investigation.

Four close friends go hunting in the bush on a stag trip. But the groom-to-be never comes back – he was shot through the head. Initially this would seem to be just another tragic hunting accident amidst picturesque New Zealand bush. The only problem is none of the remaining three friends own up to pulling the trigger that fired the lethal bullet - yet all three had discharged their rifles – with no deer to prove it. The question is – who shot Hayden Renner? Was he mistaken for a real stag or was there something more sinister at play?

The Brokenwood Cheetahs are a local rugby team of legendary status. Their losing streak of 50 straight games has broken national records. So when their hapless coach, Arnie Langstone, is found dead - stripped naked and strapped to a goalpost - some think it might be blessing in disguise – perhaps now they might start winning again. But amidst this DSS Mike Shepherd is perplexed by several other issues. Firstly, why was a pair of women’s underwear stuffed down Arnie’s throat? And what do the neatly embroidered initials ‘G.G.’ signify? But then a second body is discovered and Mike and his team are stretched to the limit. Is this the work of a serial killer or merely a puzzling co-incidence?

Holly Collins is not only DSS Mike Shepherd's favourite country musician she's also playing in Brokenwood. Unfortunately it turns out to be her final gig. When she is found electrocuted it appears to be a rock'n'roll suicide. But then again it could have been a drunken accident - or, as Mike suspects, it is perhaps something less obvious. With a careless note scrawled in lipstick the only clue, Mike has to set aside his personal interest in the victim and strike the right note with Holly's dysfunctional band members: Slim Fingers, Waylon Strings and Jesse James. But the more he finds out, the more he needs to know and the less he likes what he learns.

The Frog and Cheetah’s publican, Ray Neilson, has branched into tourism with his ‘Lord of the Ringz Tours’ tailored to non-English speaking tourists. But when Ray’s wife Debbie is discovered dead under a giant foam spider in a supposed film location of Mirklewood things get ‘mirky’. Especially when Debbie’s cause of death is revealed to be from New Zealand’s only native venomous spider – the Katipo. But if it was, how did one spider administer ten times the lethal dose?

Brokenwood is in mourning as beloved local poet Declan O’Grady is being farewelled at St Judas Church after being struck down by cancer. But things go from bad to worse when his coffin accidentally falls from the hearse revealing that the corpse inside is not Declan but a young woman identifiable only by a notable scarlet tattoo.

With December approaching Brokenwood is alive and well with Christmas spirit. That is until a gruesome sight confronts Mike and his team; Santa Claus with his throat slit. Or as Mike insists – ‘not Santa, but a man dressed in a Santa suit’. The man is in fact the much-loved local Mayor, Evan Whitestone, who dresses as Santa every year for the Christmas parade. But with local elections looming, attention turns to his four rivals for the mayoral chains. Each of them has an axe to grind with Evan or, in this case - a cut throat razor.

When Kristin, Breen, and Gina celebrate Mike’s birthday with a picnic in Brokenwood Domain, they are witness to a fatal skydiving accident. To make matters worse, Kristin knows the victim – entrepreneur Andre Barrington, an ex-boyfriend who moved onto another woman – Grace Turner, an adrenalin junkie and fellow skydiver. As the investigation unfolds, an unsettling truth is revealed. Andre’s parachute was never going to open as the cords were severed. Was it an elaborate suicide or was Grace having second thoughts about Andre? Then again – Andre’s older brother Felix was tired of living in his shadow, and his mother Lorraine’s maternal love verged on the side of sinister. Both of them were jumping with Andre too. And what about Andre’s business partner Dean Young, who was less than impressed by Andre’s work ethic? Mike and his team are forced to confront the old adage: ‘what goes up must come down’ – but not always in the way you want.

Charity Highmore-Browne is the owner and curator of Brokenwood's Historic Village. A stickler for all things Victorian, Charity lives in a time warp. Her sudden death by an arrow brings Mike and his team into the realm of New Zealand's colonial past as they deal with a blacksmith, a missionary and the local postmaster. Not to be overlooked is Charity's sister who once represented the country at the Olympics, missing out on a bronze medal in archery. As the investigation brings up questions about Charity's lifestyle and the mysterious disappearance of her husband seven years earlier, the team are faced with the possibility that Brokenwood is dealing with its first serial killer. Things are complicated further when Mike is forced out of the office due to a health scare and Kristin takes charge of the case. But can Mike truly hand over the reins?

Sunset Manor is a rest home in Brokenwood for the aged and bewildered. The new resident is Edward Alderston. Having recently lost his wife, his family has decided Sunset Manor is the best place for him, especially now that the Alzheimer’s is taking hold. Mrs Marlowe is a regular visitor, offering sing-alongs at the piano for the residents. But Edward is hoping for more of an ally than that. He’s planning an escape. In fact he’s been practicing. The only problem is he can’t remember the plan. But when a man is found with a Samurai sword through his back floating in his swimming pool in the neighbouring street, Edward’s exact whereabouts becomes of real importance.
