Hiro and Ando land 5 years into the future and they find a timeline of the past events hat happened before and after the explosion that occurred. Then Hiro and Ando find the future hiro. They all started to have a chat but soon after they arrived Matt and his team just came in and took Hiro but Ando and future Hiro got out and they said the only person that could help us is Peter Petrelli because people with powers are now being called terrorists. Matt was trying to read Hiro's mind but could get nothing except from 5 years ago so he thinks he caught the wrong guy.
Then future Hiro takes Ando to Las Vegas where they find Jessica/Niki as a stripper and she tells them where they can find Mr. Bennett. While there we see Peter is with Niki and you see Peter use his powers a bit.
Later we see Mr. Bennet helping other people with powers so they wont get caught because there blood is different. So future Hiro and Ando both come to see him and tell him that Claire is alive because Peter saved the Claire in the past. But he already knows shes alive.
Mr. Bennet then goes to Claire where she works as a waitress at a diner in Texas and tells her that other people know that she is here and tells her to leave. Though Claire doesn't want to leave because shes in love with a Texan and are getting married but he doesn't know her power.
President Petrelli has made people who have these powers evil and not good and there is a bounty out for them. We find out Matt works for the Department of Homeland Security and tries to wipe out as many people with powers.
Matt finds out where future Hiro is but he thought he already caught him but then Peter comes in he is invisible and then freezes time and teleports future Hiro and Ando out of the place before they get killed. Also Ando learns that he was killed in the explosion in New York.
Mr. Bennet goes to talk to Matt and tells him where Future Hiro and Ando are. Matt thanks him for what he has done but points the gun at Bennett and reads his mind to find out where his daughter is and kills Bennet.
Later Matt is at the diner Claire works in and takes her to the Petrelli mansion were she meets her dad Nathan. Nathan starts to yell and tell her how important she is so she runs off and he puts his hand up and she stopped moving. Then you saw that Nathan was really Sylar and it was to late to save Claire so she died.
Peter and Niki/Jessica are having an argument and she gets upset and makes him tell her that he was the one who exploded not Sylar Nathan just said it was Sylar so Peter could be protected. Then Peter leaves and meets up with Ando and future Hiro to save Hiro and get him out of police custody. They use there powers to get through but need help getting to Hiro because the Haitian is blocking there powers but then Mohinder finds out that this could all be changed if Hiro goes back and kills Sylar. So Mohinder kills the Haitian and now Peter and future Hiro can use there powers again. Just as they thought now its over future Hiro is shot and has the picture of what Hiro has to do and then he dies. Peter then gets pulled out of that room through the door and he sees Nathan and he tells him that Nathan would never and could not do this so Sylar reveals himself. Than they talk but they are about to battle Sylar with ice and Peter with Fire but on the other side of the door Mohinder is trying to keep the door closed and Hiro and Ando go back to the past and Hiro says now the hard part starts and it shows him killing Sylar.
