An angel is cast out of Heaven and to redeem herself must defend humanity.

Based on the comic book series, Avengelyne is an angel who fights the forces of evil and often finds herself face-to-face with demons and monsters. She was the most feared warrior in Heaven's Warhost, having single-handedly broken into Pandemonium, the outer fortress of Hell, to confront the Devil himself. She is a fallen angel, banished from Heaven by God after being tricked into questioning his love for humans. Avengelyne was stripped of all her angelic abilities, other than her great strength and her blood, which, once extracted from her body, could be used as a weapon or a miracle once empowered by quoting verses from the Bible. Avengelyne uses her powers to fight demons on earth and is being groomed to be humankind's last hope in a coming Armageddon.
