WHILE SEVERAL HEROES FACE OFF AGAINST THE "NIGHTMARE MAN,” PETER LEARNS JUST
HOW DEADLY THE VIRUS CAN BE -- When one of his forgotten abilities suddenly
manifests, Peter (Milo Ventimiglia) and Caitlin (Katie Carr) get thrown into
a crisis situation, and learn first-hand just how deadly the mysterious virus
striking people with abilities can be. Suresh (Sendhil Ramamurthy), Matt
(Greg Grunberg), Nathan (Adrian Pasdar), Niki (Ali Larter) and Bob (guest
star Stephen Tobolowsky) band together to fend off the "nightmare man’s"
attack. Despite Claire’s (Hayden Panettiere) best efforts to keep them
apart, West (Nick D’Agosto) learns that the man who kidnapped him as a child
is her father (Jack Coleman). Meanwhile, in feudal Japan, Hiro (Masi Oka) and
Kensei’s (David Anders) legendary journey takes a dramatic, final turn.
