S. team visits the past to try and erase the Chinese attack in the first place. The impacts of interfering with time go far beyond anything Agent Hessman and his intrepid team of time defenders could have imagined-worlds beyond, in fact. Their efforts bring them face-to-face with an alien being, Sonsa Tabbak, who arrives to stop human time travel before a universal catastrophe can occur.What happens next changes everything, everywhere, forever.
