Darcy's mother is getting out of jail. Ten years ago she was convicted of throwing Darcy's baby sister off a fifth floor balcony. Kat survived, but Darcy has spent the last decade raising his sister, giving her the love and support she has been denied by an absent mother and an uncaring father. Now, with their mother about to be released, their father is determined to return the children to their mother's care. Darcy is horrified, and adamant that he will not subject his sister to the woman who once tried to murder her. Struggling to control the anger that has consumed him, Darcy is forced to confront his feelings and engage with the outside world.
