It's been five years since the public became aware of the existence of evolved humans or "EVOs" who possess incredible, supernatural abilities. In that time, the public has grown to either fear or revere EVOs. An online community forms around the rallying cry of the anonymous Hero_Truther, who seeks to humanize EVOs in the wake of lies, slander and fear mongering. Among those posting their personal stories is Phoebe Frady, who is encouraged to document her origin story by her brother, Quentin. But as Phoebe struggles to control her power, she attracts unwanted attention from a mysterious new company.

The prequel series begins as the mysterious Hero_Truther puts out a rallying cry for EVOs to declare themselves by telling personal stories in the wake of lies and fearmongering. This prompts Phoebe Frady to reveal to her brother, Quentin, that she can manipulate shadows.

Quentin encourages Phoebe to continue documenting her story when she begins college, where she becomes fast friends with her roommate Aly (Greta Onieogou). As Phoebe's power grows, she discovers that there's much more to her ability than she initially realized, but Quentin worries that it may be too much for her to handle.

After a pro-EVO demonstration at the college gets out of hand, Phoebe is arrested and forced to register in a national database. When Phoebe is approached by Harris (Clé Bennett) with a job offer at the fast-growing tech company named Renautas, it raises Quentin's suspicions.

Phoebe goes missing after an argument with Quentin over her ongoing nightmares.

In the wake of tragic events on June 13th, Quentin refuses to believe his sister was involved in the attacks and believes Renautas was behind Phoebe's abduction.

Hero_Truther's true identity is revealed when Quentin brings him evidence that connects Renautas to the Primatech Paper Company, leading Quentin to track down a former Primatech employee: Noah Bennet aka HRG (Jack Coleman).

In an effort to get answers, Noah Bennet joins forces with Hiro Nakamura to return to the day of the tragic events of June 13, 2014 that set everything in motion. On the verge of delivering a speech to commemorate the event, Mohinder Suresh receives a dire message from Angela Petrelli about Erica Kravid's true motives. In Japan, Hachiro Otomo makes a calculated move against Hiro Nakamura. Meanwhile, a much happier Luke and Joanne come to Odessa in hopes of finding a cure to their son's ailment.

In the wake of an unspeakable tragedy, Erica Kravid puts her dark plan into motion with Renautas. Hiro and Angela are tasked with an important mission that could change the course of humanity. In Odessa, a distraught Luke and Joanne come to realize their tragic mission after the loss of their son. Meanwhile, Noah Bennet has an unexpected reunion with Matt Parkman. In Japan, the origins of Miko come to light. Elsewhere, the truth behind Carlos' military service is revealed.

Joanne Collins continues on her pursuit of Damen Peak. He notices that she is following her, so he quickly maneuvers around the streets. Damen parks his car hoping that Joanne would not know where he went. However, his wife calls him over the car phone. As he tries to talk quietly, she insists on talking to him. Joanne realizes where Damen is hiding and so he drives away.

Joanne Collins begins a recording, most likely to Renautas. She is speaking about her new target, Damen Peak. Damen is seen having a meeting with Jim and others. He claims that he has enjoyed getting to know Jim and is glad that Jim trusts him with his dreams and fears. Damen persuades Jim to agree with him. They all get up and leave the meeting. Damen leaves the building in his Cadillac CTS as Joanne begins to follow him.

As Damen and Lilly leave the house, he tells her that someone is attempting to kill him. She asks him why as Joanne Collins shows up and claims that it is because he is an evo. She points a gun at them and Damen asks her to stop. He uses his ability of persuasion to try to get her to stop. Damen claims that he is just a human being with a modest talent. He asks Joanne if she has a talent and she replies that she is a good shot. Damen persuades Joanne with his mind to just walk away. Joanne walks away, leaving them unharmed.

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.
