Following Noah's mysterious disappearance, Luke and Malina unite to rescue Tommy and save mankind. At the mysterious Sunstone Manor, Carlos and Farah fight alongside The Haitian to take down Matt Parkman and free the prisoners under his control. Tommy and Miko join forces against Erica and her brutal plan for the future.
One year ago a terrorist attack in Odessa, Texas destroyed the city and the government blamed those with extraordinary abilities. Consequently they must live in hiding or flee from those with bad intentions. Two such vigilantes, Luke and Joanne, lost someone important in the event and seek revenge.
Noah Bennet, aka HRG, is also in hiding, but is found by the conspiracy theorist Quentin Frady who tries to show him the truth behind the Odessa tragedy. While they're in hiding, some of them are discovering their newfound skills. Malina is a courageous girl, who was brought up much overprotected, but she finds out she is destined for greatness. Erica is the head of the highly successful tech conglomerate called Renautas, and she has her own dark goals. Awkward teen Tommy tries to live a normal life and just has eyes for his dream girl, Emily, but he discovers a new terrifying ability that makes his will almost impossible. Meanwhile in Tokyo, Miko, a unique and quiet girl is looking for her missing father, but she hides an extraordinary secret that can be dangerous to her. Somewhere, a singular type of hero is emerging through Carlos, a former soldier.
As long as new Heroes are emerging, some heroes of the past such as Hiro Nakamura, Matt Parkman, Mohinder Suresh, The Haitian, Angela Petrelli, and Micah Sanders, among others, will cross paths with them. And, together, they will have their ultimate quest: save the world and mankind.
