The team have to deal with a herd of Embolotherium from the Eocene. Danny arrives with a mysterious woman called Eve who he first saw in the Future; having rescued her from Christine Johnson, they endeavour to save everyone from the stampede. Upon their return to the ARC, the team are shocked to discover that Eve is Helen Cutter in disguise, who takes Johnson hostage. Holding her at gunpoint, Helen steals the artifact and vows once again to stop the ARC's research destroying the world.
