Op and Ed, two adorable donut-shaped animals - flummels - accidentally time-travel from 1835 to modern-day Shanghai. There they discover traffic, trans fats, and worst of all, that flummels are now extinct. It's up to this bumbling pair to save themselves and their species...and, just maybe, change the course of history.

400 years after the extinction of the human race, a small group of humans are revived by an alien civilization. The colony of revived humans encounter struggles with the aliens who extinguished humankind centuries before, while trying to understand and get along with the mysterious aliens who revived them.
