In Heroes, life suddenly changes for a far-flung group of seemingly ordinary people when they begin developing superpowers. New York nurse Peter Petrelli (Milo Ventimiglia) has been having strange dreams about flying, a quirk that his politically ambitious brother, Nathan (Adrian Pasdar), wants nothing to do with. Las Vegas Web-cam girl Niki Sanders (Ali Larter) has begun to see her dangerous alter ego's reflection in mirrors, while Japanese office worker Hiro Nakamura (Masi Oka) has literally started turning back the clock. Cop Matt Parkman (Greg Grunberg) realizes that he can hear what other people are thinking, and jailbird D.L. Hawkins (Leonard Roberts) finds out that he can walk through walls. Texas cheerleader Claire Bennet (Hayden Panettiere) has discovered that she's incapable of getting hurt, and artist Isaac Mendez (Santiago Cabrera) is painting horrifying images that seem to show future events. Meanwhile, Indian genetics professor Mohinder Suresh (Sendhil Ramamurthy) is picking up the pieces of his deceased father's research surrounding a global event that could change the course of all mankind.
