The 'Hidden Assets' Season 3 Trailer Takes the Team to Spain

Police procedurals are so common in Europe that it can become hard to distinguish between them. It doesn't help that nearly all function under units that can start to feel like alphabet soup. However, the RTE series Hidden Assets has found an interesting angle that allows it to blend the police procedural with their own, homegrown favorite TV show subject: Irish Mafia dramas. The series focuses on the CAB, the Criminal Assets Bureau, the team of detectives tasked with rounding up all of the ill-gotten gains after a criminal enterprise is dismantled.

It's a brilliant combination: much of those ill-gotten gains end up on the continent, so the show is half-filmed in other countries, making the first two seasons a co-production, and allowing the show to establish itself before RTE took sole control.

Seasons 1 and 2 were Irish-Belgian affairs, with Season 1 featuring Irish DS Emer Berry (Angeline Ball) teaming up with Belgian Inspector Christian De Jong (Wouter Hendrickx) to track down the Melnick Family. Season 2 returned to that same case a few years down the line, now with DS Claire Wallace (Nora-Jane Noone) heading up the CAB team with De Jong.

Season 3 opens with a new case, with DS Wallace leading the team in a case that brings them to the Basque Country.

Taking the story to Spain's Basque Country also introduces another special police force Americans won't be familiar with: the Ertzaintza (People's Guard), an autonomous police force unconnected to the country's national police.

Here's the Season 3 synopsis:

The new season kicks off with the brutal murder of investigative journalist Olatz Alzola and her family in Bilbao. When the killings are linked to a past CAB raid in Ireland that ended in tragedy, DS Wallace is drawn into a dangerous web of crime and corruption.

Season 3 sees the return of Nora-Jane Noone (The Ipcress File) as DS Claire Wallace alongside core cast members Cathy Belton (Miss Scarlet) as Norah Dillon and Aaron Monaghan (The Banshees of Inisherin) as DS Sean Prendergast, who have appeared in all three seasons.

The rest of the Season 3 cast consists of new faces, starting with Iñigo Gastesi (Argi Gorriak) as Oficial Jon Beitia and Charlotte Timmers (Professor T) as Oficial Lore Velasco, the Ertzaintza team assigned to the case. Season 3 will also introduce Catherine Walker (Versailles) as Niamh Bennett, Dónall Ó Héalaí (Crá) as Detective Liam Boylan Frank Laverty (Say Nothing) as Anthony Pearse Tony Doyle (Kin) as Brian O'Neill, Rebecca O'Mara (Line of Duty) as Alice Heaslip, and Steve Wall (Vikings) as Martin Dunlop.

Like Seasons 1 and 2, Season 3 of Hidden Assets will run six one-hour installments, written by series creator Peter McKenna (Kin), with Susan Connolly, Cara Loftus, and Mary Fox & Marty Thornton. Director Kadir Ferati Balci returned to helm episodes as lead director.

Hidden Assets Season 3 premieres exclusively on Acorn TV on Monday, January 19, 2026, with one new episode a week through the end of February.
