Overview: Nicola Walker (Last Tango in Halifax) and Sanjeev Bhaskar (The Indian Doctor) lead a powerful ensemble cast in this highly-acclaimed, thrilling third season of the UK-set crime drama.

DVD Verdict: DCI Cassie Stuart and her partner, DI Sunil "Sunny" Khan re-open cold murder cases from decades past, throwing lives into turmoil as they seek justice for their unforgotten victims.

In the six-episode first season, when the body of a young man is discovered in a derelict building, DCI Cassie Stuart is called in to investigate with her partner, DI Sunil Khan.

In the six-episode second season, the detectives have been tasked with the investigation into the identity of skeletal remains which had been sealed in a suitcase many years earlier, and that were recently dredged from the River Lea in North East London.

Here in the gripping six-episode third season, when human remains are found by a highway, Cassie and Sunny are called to the scene. Dogged work leads the team to Hayley Reid, a 16-year-old girl who went missing on the eve of the millennium.

The police's failure to find out what happened to Hayley wrecked her family's life. Cassie is determined to correct the mistakes made by the original investigating team, no matter the personal cost.

A close-knit group of old school friends hold the key to what happened. Doctor Tim Finch, television presenter James Hollis, failing salesman Pete Carr, and artist Chris Lowe.

As the four suspects find themselves under the spotlight, their tight bond is put to the test. They all have secrets in their past - events that have pulled their lives apart.

None of them are quite who they first seem to be, but is one of them capable of murder?

As always, the performance of the lead actor, Nicola Walker, is outstanding, as is the performance of her primary supporting actor, Sanjeev Bhaskar.

A brilliantly written, acted and directed series as aforementioned, Walker is such a wonderfully subtle and real actress that you could watch her, and believe her in anything she put her mind to on TV.

As always, the series is a who's who of top British theatre and television talent and all six of the episodes are gripping and, at times, quite literally exhaustingly stressful to watch … but in a really good way, of course!

Indeed, much like the first two seasons, this third outing of 'Unforgotten' is a decidedly intelligent, intriguing, and gripping murder mystery and drama, and I, for one, found it to be extremely engaging and entertaining.

Both seasons feature superb plot and character development, as well as great acting performances, and it definitely merits a binge watching evening, of that you have my word. This is a Widescreen Presentation (1.78:1) enhanced for 16x9 TVs and comes with the Special Features of:
