Five Years Gone picks up where we left Ando and Hiro, in Isaac’s apartment where they end up finding Future Hiro. Future Hiro explaines what happedned to the city, Sylar has exploded and killed millons of people. he has been working on a timeline to prevent all this from happening, and he also thought he found a way. (Telling Peter to “Save the cheerleader, save the world”) Hiro and Ando inform him that Peter did indeed saved the cheerleader, but he did not kill Sylar. Future Hiro tells them to go back on the election day to kill Sylar, but at the time Matt Parkman, now the head of Homeland Security, Haitian and his men break in and capture Hiro. Ando and Future Hiro excape. They agree on freeing Hiro and sending him back to kill Sylar. Future Hiro teleports them to Las Vegas to get help from Peter Petrelli.

In Las Vegas, they go to Niki’s club where she dances and runs to find Peter. Niki and Peter has become lovers. She tells them Peter has no interest in helping them. Then they ask about Bennet, she tells them that he’s still in Texas. After they leave, Peter appears on the counter. He’s been there all the time watching them, invisible. They argue about Hiro and Ando and that is where we learn Micah and DL are both dead.

Parkman questions Hiro about events over the past five years and becomes angry becaouse Hiro can’t remember them. He tries to read his mind on and on but there’s nothing in there. He still doesn’t seem to realize that the Hiro they have captured is the younger Hiro. Parkman calls the President, Nathan Petrelli, to inform that they have Hiro Nakamura. Nathan seems to have thoughts about this being a trap. he wants Matt to use more power to get anything out from him. Nathan later meets with Mohinder, the top science advisor. They talk about explosion and the possibility of curing the abilities of superbeings. When Mohinder points out that it is impossible to take their abilities back, Nathan tells him about his plan, extinction. He tells Mohinder that he is going to announce the world that hey have found a cure, which is a false vaccine that will put an end to the species kind.

While Parkman forces Hiro to talk about his plans for tonight, the 5th anniversary of the explosion, he gets a call about Mohinder being at Isaac’s studio looking at the timeline.

Back in Texas, Primatech Paper Company. Mr. Bennet has become a man who helps people with special powers to hide and be safe. Ando and Hiro asks help for some of the people that he helped to rescue. (DL, Candice, Molly Walker) He refuses until Ando tells him that Hiro saved Claire by telling Peter Petrelli to save her. Mr. Bennet seems to agree to help them.

Mohinder and Parkman discuss about the meaning of the strings. Mohinder starts to believe Hiro’s theory, that he can change the future with his time traveling ability. Parkmas still doesn’t believe in that.

Claire has became a waitress, making plans about her wedding with her fiance. While talking the boy points out the creepy man in her section, who turns out to be Mr. Bennet. He warns her that someone knows about her and she needs to leave immediately. She hesitates for a moment but then takes the money. while they were talking something on tv appears, people are taken away from their homes as a matter of Homeland Security.

While waiting for Mr. Bennet, Ando asks Future Hiro about what has happened to him. Before Hiro answers, Parkman bursts in and captures Future Hiro. He gets shocked to find another Hiro and finally believes that Hiro can time-travel. Then, Peter comes in and stops the time, teleports Ando and Hiro away, leaving Parkman with nothing.

HGR comes back to his company. We learn that he gave in Hiro and Ando, believing Hiro is a terrorist and can do harmful things, and he will be allowed by the government to save the harmless ones. While they talk, we learn HGR is helping Parkman’s family to hide too. Bennet sees his assistant shot on the floor just before Parkman pins him down and ends the arrangement. He puts a gun to Bennet’s head then he gets Claire location and shoots him.

Claire convinces her fiance to elope and leave. Parkman’s there too, taking her into custody.

Mohinder questions Hiro abot the past while holding a 9th Wonders issue that Hiro has never seen. (remember the one Isaac sent before he was killed.)

Peter, Ando and Future Hiro are in Peter’s apartment. Peter tells Ando that he died in the explosion, Hiro became grim after his death and he became obssessed about fixing the past because he wants to save Ando. Niki walks in.

Mohinder and Nathan, in Isaac’s studio, talk about Hiro. Mohinder tells Nathan that Hiro has found a way to stop Sylar. Nathan doesn’t believe Hiro can succeed. He still wants to go with his plan. Parkman arrives and tells Nathan that there are two Hiros, and they have the young one. Parkman wants to put him down, but Nathan decides taht he wants Mohinder to do this. Parkman also reveals that he has found Claire.

Claire meets with Nathan. Nathan talks about Candice helping him to get the presidency. He says he has met a lot of special people, he has gained a lot power and now he doesn’t want any other person with power because he doesn’t want the competition. This is where we see Nathan is actually Sylar himself. Then he slices Claire’s head and takes her power. It seems that Claire’s power is the last one Sylar needs.

Future Hiro and Ando talks about how things have changed and weren’t what they expected. Peter and Niki have a fight. Peter talks about DL, Micah and Jessica being gone and she should accept her loss. He explaines Niki why he needs to help Hiro by revealing that it was him who exploded, not Sylar and Nathan blamed it on Sylar to protect him.

Nathan (or Sylar should i say) giving a speech while Peter, Future Hiro and Ando try to save Hiro. Mohinder and Parkman are getting ready to execute Hiro. With Haitian upstairs, both Peter and Future Hiro know they can’t use their powers. Mohinder injects the poison to Haitian, just like Isaac has drawn in 9th Wonders. Peter, Ando and Future Hiro arrive while Mohinder tells Hiro to stop Sylar. Hiro says he doesn’t know how to go back in time by himself, Future Hiro tells them he will get him but Parkman shots him in the back. Parkman calls Nathan/Sylar to tell Haitian his down. Nathan flies wihtout caring that he is infront of a huge crowd.

While Future Hiro dies, Nathan pulls Peter through out the door and throws him down the hall. Peter recognises that he’s not Nathan. Sylar reveals himself and they both nuke up and the battle begins. While they are fighting, Ando assures Hiro that he can take them back in time. Hiro succeeds and takes both of them on top of the Deveuax building.
