About the Show: Dr. Jason Cole (Steven Pasquale, "Rescue Me") is a highly respected neurosurgeon who has it all - a lucrative career, confident charm and the gift of compassion. But he also has a deep, dark secret. One morning, after waking up disoriented in a wrecked hotel room amidst near-naked women he's never seen before, he knows one thing: it happened 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 Ian Price. For years Jason has 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 is 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 must 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.
