In a desperate attempt to keep his son from Jason, he kidnaps him and hides him from both Jason and Olivia. Meanwhile, Ruben closes in on thehug drug but isn't sure if he should use it - and, if so, who of Jason or Ian he should use it on.
Dr. Jason Cole is a highly respected neurosurgeon who has it all - a lucrative career, confident charm, the gift of compassion. But he also has a deep, dark secret. One morning when he wakes up disoriented in a wrecked hotel room amidst several near-naked women he's never seen before, he knows one thing: it's happening again.
Every night at the same hour, something inside Jason changes, leaving him almost unrecognizable - seductive, devious, borderline sociopathic. This new man is his dangerous alternate personality who goes by the name of �Ian Price'. For years he's battled Ian, keeping him in check with a powerful experimental sedative.
But now his - their - body has developed a resistance to the serum, setting Ian free once again. And to make matters worse, after being suppressed for so long, Ian's hell-bent on taking revenge on his oppressor. With everyone Jason cares about at risk - patients, friends, coworkers and even the woman he loves - he's got to stop Ian once and for all. Will they find some common ground, or will they bring each other down? Hell hath no fury like an alter ego scorned.
