After a riveting first-season cliffhanger, round two of this top-rated superhero drama finds Hiro (Emmy nominee Masi Oka) transported to 17th-century Japan and surrounded by samurai warriors -- just in time for a solar eclipse. Can he fight his way back to the 21st century? Meanwhile, Nathan (Adrian Pasdar) has become an alcoholic, Peter (Milo Ventimiglia) is roaming Ireland with amnesia, and Molly (Adair Tishler) is having chilling nightmares.
