20 years after angels descended from heaven to lay waste to the human souls they felt God had favored over them, a reluctant "savior" must arise to protect Vega, the last remaining stronghold of humanity. The savior has more to fear than just angels, as the elites of this new society conspire to gain power for themselves.

Alex rejects his new role as the Chosen One, but then a sleeper threat in Vega forces him to spring into action and protect the ones he loves. Meanwhile, Michael meets with Gabriel one last time before the war between angels and mankind reignites; and Gen. Riesen and David Whele try to tie up loose ends.
