It’s been 27 years since Earth's destruction. Surviving humans have made their departure to the orbiting military space station, Titan II. Riley Karlsson, a covert time travel agent, is tasked with averting the coming worldwide apocalypse. Through many attempts, he struggles to find the solution to averting the fast-approaching doom. And suddenly, he disappears.

Bethany Clarke, a scientist who searches for Riley after his mysterious disappearance, remains the only one who believes that Riley is still out there somewhere. The two soon come to realize that Earth's apocalypse is, in fact, the least of their worries, as there are much bigger problems to handle than saving whatever remains of human civilization.
