"Falling Skies," TNT's post-apocalyptic sci-fi drama, returns for a third season on Sunday. Noah Wyle is still fighting aliens as a former history professor now in command of a militia — and now a new alien army arises.

What does this new species of extraterrestrial have in store for the humans?

Overlords, new ETs and a love triangle get the season off to a running start.
