In an isolated village in the north west of Ireland, a murder investigation begins when Garda Barry Roche finds a body buried in the bog

​It’s already aired on BBC1 Northern Ireland and the Irish channel TG4, and now the Irish-language drama Crá is coming to BBC4.

The title roughly translates as Torment or Angst, which should give you some idea of the tone, and it’s also drawn comparisons to Scandi-noir. So, get ready to be hooked at it begins with a double bill.

Set in a remote village in Donegal, the plot begins when Garda Barry Roche (Alex Murphy) finds a body buried in the bog.

The discovery sparks a murder investigation, which turns out to be very close to home for Garda Conall Ó Súilleabháin (Dónall Ó Héalai) as the body is identified as his mother, Sabine, who disappeared 15 years earlier. Due to his personal connection to the case, he is barred from working on the investigation.

Meanwhile, determined young journalist Ciara-Kate (Hannah Brady) hopes the story can help boost her career as she covers it for her true-crime podcast. Conall realises that this means she can ask questions and talk to people he wouldn’t be able to, even if he was officially investigating, so they team up to try to solve the murder.

Can they manage to break through the local community’s wall of silence and moral codes to unearth the truth? And will there be any repercussions as Ciara-Kate broadcasts every twist and turn to her growing audience?

The social-media angle puts a fresh twist on a story that the makers believe mixes the old and the new. Darach Ó Tuairisg, Executive Producer for Fíbín Media, said: “Crá is a unique and thrilling exploration of justice, secrets, and community, set against the striking backdrop of Donegal.

“From the beginning, we knew we had something special with this story, and working with such a talented cast and crew has only elevated it further.

“The series brings together the richness of Irish-language storytelling with a modern, suspenseful narrative that we believe will captivate viewers.”

The initial reactions on social media when the show aired in Northern Ireland suggest that belief was justified, and now Cra has a chance to find a whole new audience.

The good news for anyone hooked by the first episode is that the second instalment follows immediately afterwards.

Sabine’s funeral takes place, and there’s another reason why Conall can’t officially work on the case – as far as some of the locals are concerned, he’s a prime suspect. The finger of suspicion is also pointing in the direction of Sabine’s husband Art. Conall is on a mission to find out whether his father really was involved, but there’s a shock in store when a ghost from his past returns.

Meanwhile, Ciara-Kate follows her own theory that Sabine was having an affair at the time of her death.

If you can’t wait until next week for episode three, you can always watch the whole series on BBC iPlayer.

Barry McGovern, Róisín Murphy, Tara Breathnach, Caoimhe Farren and Alan Mahon are among the supporting cast.
