Years have passed since Sean Barker came into contact with the Guyver unit and became one with it. Having destroyed the Kronos Corporation, the company behind the Guyver and the creatures known as the Zoanoids, Sean tries to use his powers to fight crime, but the Guyver's desire to kill leaves him emotionally and spiritually tortured. After watching a news report of an archaeological dig in the mountains of Utah that remind him of the visions he has been receiving from the Guyver unit, Sean travels to the site. On his way, he meets Cori Edwards, a researcher at the dig and the daughter of head archaeologist Marcus Edwards. Upon arriving at the archaeological site, he sees the fossil of a Zoanoid that resembles his past nemesis Lisker. Later that night, Sean finds himself once again battling a Zoanoid that has been terrorizing the camp, but it disappears when Cori and her team arrive. Sean is later on questioned by Commander Atkins, who reveals to him that the Guyver only destroyed the Kronos Los Angeles, and that another branch of Kronos is behind the Zoanoid attacks in the camp.
The next day, the archaeological team unearths an alien ship. After the team spends hours attempting to breach the hull, the ship mysteriously opens a hatch for them to enter. Inside, Sean tries to communicate with the ship, demanding to have the Guyver removed from him. Meanwhile, Cori discovers another Guyver unit, but Arlen Crane, who actually works for Kronos, confiscates it from her. After Sean tells her the truth about Kronos, Cori goes out to confront Crane, but overhears an operation to terminate all non-Kronos personnel from the site and is nabbed in the process. Crane reveals himself as a Zoanoid to Sean and proposes an alliance to help activate the ship to turn them both back to normal, but when Sean refuses, he is knocked out and sedated by Crane's female security head Brandi. Meanwhile, the security jeep escorting Cori is attacked by a Zoanoid, which is revealed to be her father. The two officers transform into Zoanoids and battle Marcus. Sean escapes captivity with the help of Atkins and rushes to save Cori. He kills the two Zoanoid officers before revealing his identity to Cori.
Back at the site, Atkins and his commandos stop Crane from executing the archaeological team and has them evacuate the premises. Sean tells Cori they must destroy the ship. Transforming into Guyver, Sean communicates with the ship, discovering that the Zoanoids were a failed experiment by an alien civilization. The aliens then attempted to equip the human race with Guyver units to combat the Zoanoids, but the humans rebelled. With Cori once again at gunpoint, Crane orders Sean to deactivate the Guyver and surrender. Marcus intervenes, but is mortally wounded by Crane. Atkins is cornered by Brandi, but he kicks her against a power generator before shooting her dead. Sean confronts Crane, but Crane transforms into the Guyver Zoanoid, becoming stronger and faster than Sean. In the middle of the fight, Crane stabs Sean in the abdomen, but Cori shoots Crane's Control Metal. Sean then removes it, and uses his Mega Smasher to put Crane out of his misery. Using his Control Metal, Sean tells the ship to return to its home planet. Following the incident, Atkins attempts to recruit Sean into joining the government's underground war against Kronos, but Sean drives off with Cori instead.
