Kieran Watts isn't like Lucas. He's rude, obnoxious and reckless, and Ellen can only watch in despair as her son falls deeper under his influence.
Then Ellen's whole world implodes and she embarks on an obsessive need to get revenge.

There is nothing you won't do for your children - even murder . . .
