Still picking up the pieces after the death of Denis and the cover up that followed, Val Ahern's world is rocked once again when a stranger turns up on her doorstep. The stranger introduces himself as Finn – Denis’ estranged son, and his existence is an unwelcome surprise for the family. Abandoned to grow up in foster care in Britain, Finn wants to get to know his family but his appearance coincides with what seems to be an orchestrated campaign against the family, as each of the Ahern daughters has their lives targeted and exposed.

As Val’s daughters, initially hostile towards Finn, start to warm to him and invite him into their clan, conflict between the girls and Val ensues. Can Finn break up the family Val has fought so hard to protect? Has that been Finn’s plan all along? Who is behind the escalating campaign of intimidation against the Aherns? And just what other family secrets has Val buried along the way as she strives to protect the family name?
