Kat and Scott Hamilton are dealing with the hardest of losses: the death of their only child. While Scott throws himself back into his law practice in Los Angeles, Kat is hesitant to rejoin the workplace and instead spends her days shell-shocked and confused, unable to focus. When an unwelcome face from Kat past in England emerges -- the beautiful and imposing Sarah Cherrington -- Kat's marriage is thrown into a tailspin. Now wealthy beyond anything she could have imagined as a girl, Sarah appears to have everything she could need or want. But Sarah has an agenda and she wants one more thing. Soon Kat and Scott are caught up in her devious games and power plays.
