Four estranged siblings are reunited – before a brutal murder takes place 15 days later...
A shot rings out in an isolated farmhouse as a young man is killed by an unseen hand. Two weeks previously, four siblings return home to scatter their mother's ashes and read her will, little realising that this family reunion will end in murder.
Rhys is haunted by memories of events at the lake, where his father drowned five years ago. Meanwhile, domestic tensions rise as the family farm is left to Huw, who reveals a devastating secret.
Nia and Michael's affair intensifies amid the acrimonious fallout which follows the discovery of Rhys' parentage. He goes missing and the family fear for Rhys's safety, as Joy goes into labour. Meanwhile, Sara realises Gareth has a secret and is determined to find out what he is hiding.
Michael turns the tables on Nia, forcing Sara to come to her sister's rescue. Baby Cai goes missing, sending Rhys into a destructive spin that ends in him giving the family an ultimatum to leave Dolwen. He has made enemies and his time is running out.
