Photo Flash: Cast Photos for NBC's DO NO HARM

NBC has just released the promotional cast photos for its freshman drama series Do No Harm - check them out below!

DO NO HARM premieres Jan. 31 at 10 PM on NBC.

Dr. Jason Cole (Steven Pasquale, "Rescue Me") 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 is hell-bent on taking Revengeon 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.
