NBC’s Do Not Harm” is set to premiere in just a little over a month, and with that comes another promo, this one entitled “He Becomes Me.”

“In “Do No Harm,” 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’s hell-bent on taking revenge on his oppressor. With everyone Jason cares about at risk – patients, friends, co-workers 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.”
