Chris (voiced by Kevin Dorman), a mercenary affiliated with BASS, was ordered to go to a mansion to investigate an arms smuggling case. He met the international wanted criminal Glenn (voiced by John DeMita) there. After several rounds of fighting, Glenn fled. University professor Rebecca (voiced by Erin Cahill) was studying the time it takes for the dead to resurrect and injure people. She discovered the existence of a new virus and quickly developed an antidote for the virus. However, at this critical juncture, the institute was attacked by terrorists. Fortunately, Chris arrived at the critical moment and rescued Rebecca. Afterwards, the two met up with Lyon (voiced by Matthew Mercer), a member of the DSO, a direct unit of the US President. The three discovered that Glenn's real target was the new virus. He wanted to create a highly destructive biochemical crisis.
