Drama series in which people all over the world deal with their newly discovered superpowers. Hiro follows respected businessman, husband and father Arthur Petrelli in the days before he died, to discover what drove him to create Pinehearst and strike at Angela. Later, a moment unfolds where Sylar, horrified and guilt-ridden, might have stopped his murderous pursuit of abilities if H.R.G. and Elle had swayed from their monstrous assignment.
