Smother

When Val Aherns' husband Denis is found dead at a foot of a cliff close to their home the morning after a family party, she begins to interrogate his relationships with his family.

Val struggles to understand Grace's actions, while the local Garda look closer at the Ahern family as the investigation stops treating Denis' death as an accident.

Val looks to Mairead for support after Carl comes under fire when events from his past life in Denmark come to light. Calum has a run-in with a group of local lads.

With Calum missing, the Aherns question his recent violent behaviour and Val confronts Rory. Jenny and Frank reminisce about Denis.

Both Rory and Jenny have difficult news to break to their families. Despite Val's attempts to keep the family together, events spiral out of control at Anna's birthday lunch.

New evidence from the autopsy comes to light and the truth about what happened to Denis on the night of the party is finally revealed.
