An extremely tense Irish thriller movie is on TV tonight

The Irish thriller has an incredible premise.

He plays Ronan Callahan, a man who has just finished a prison sentence for the murder of his girlfriend, which it's alleged he committed whilst he was blackout drunk.

Since he has no memory of the event, the victim’s father Seán (Lorcan Cranitch) has spent the intervening 15 years painstakingly digging his way through the bog on Callahan’s land in a relentless quest to locate his daughter’s remains.

With local police refusing to move the grieving father from his home, Callahan decides to join the search, hoping that he and Seán both might find some measure of closure.

The more they dig however, the more the events of that fateful night 15 years ago get called into question.

A debut feature film for directing duo Andy and Ryan Tohill, The Dig's terrific premise, its stunningly atmospheric rural Antrim setting and its dark haunted performances make it well worth seeking out.

It's airing on BBC One at 10.55pm and is also available to rent on Apple TV, Google Play, the Sky Store and Volta.
