When a researcher at the Chronos Corporation is mysteriously killed, his daughter (Vivian Wu) ; her boyfriend, Sean (Jack Armstrong) ; and a rogue CIA agent named Max Reed (Mark Hamill) all suspect foul play. Sean discovers a top-secret suit of Chronos armor called "the Guyver," which fuses to his body when he tries it on, turning him into a supremely powerful cyborg. Chronos' evil CEO, Fulton Balcus (David Gale), is enraged and sends a crew of mutant alien monsters to get the Guyver back.
