The story starts four years in the future with Claire making a poor attempt to kill a future Peter Petrelli, who then goes back in time and shoots his own brother Nathan as we saw at the end of season 2.
Then we're teased by a short Hiro and Ando sequence before we go back to present day Claire who opens the door to Sylar, he takes Claire power and now he's untouchable.
We get to meet some new characters, a cute girl who's a 'speedster' and some old ones we thought where long dead.
Suresh gets powers, yes Suresh! he works out how his powers work and things get intresting when see Angela's secret power.
