Orphaned since birth, Aaron Corbett has finally found a loving and supportive home life on a farm. On his 18th birthday, just when his world is finally coming together, a series of dark visions disturb his sleep, and he develops a confusing array of supernatural talents. An Angel reveals the truth of his mysterious origins: He is a Nephilim, the child of a fallen Angel and a human mother. But he is not just any Nephilim; Aaron is the Redeemer, the embodiment of a prophecy that has tantalized Fallen Angels for millennia. Like all Nephilim, however, he is marked for death by a group of fierce warrior Angels called the Powers.

One year after finding out that he is a Nephilim, Aaron Corbett continues on his mission to redeem the Fallen and send them back to Heaven. After Camael is injured in a fight with the Powers, Aaron and Camael visit fallen angel who can heal Camael. Meanwhile, Azazel, one of the Fallen who has been imprisoned for 5,000 years, is released to help the Redeemer fulfill his mission.

After helping Vilma escape, Aaron and Vilma are rescued from the Powers by Azazel, who tells them he can take them to the Light Bringer, an oracle who can help Aaron on his mission. Aaron begins to doubt if he is doing the right thing by sending the Fallen back to Heaven. Meanwhile, Camael has been captured by the Powers who demand to know where Aaron is.

After escaping from the Powers, Aaron, Vilma and Azazel continue on their journey to the Light Bringer. Camael escapes from the Powers and makes his way to Ariel. Mazarin begins to have doubts about his mission.

Aaron's powers are challenged in a stronger way than ever before.
