The Avengers, while on the hunt to bring down all of the Hydra bases around the world, come upon another agency with much more evil intentions. While they infiltrate this agency named Cerberus, they find a young girl who was taken at a young age and was experimented on by them. Strangely enough, she has wings. Unsure of her identity and her wings, they take her in while they continue their hunt for Hydra and now, their hunt for Cerberus. The Avengers didn't expect how much this winged girl would change their lives.
