The Avengers find out that Lucifer (the king of Hell himself) has a son. They try to contain him and use every resource and hero available to capture the prince of hell because Lucifer has just found out his son has run away and he is livid. Lucifer is very overprotective, possessive, obsessive and controlling when it comes to his son. So if the Avengers don’t find him soon, all hell will break lose. But Lucifer’s son doesn’t want to be found and is making it harder for the Avengers. But as more and more demons and imps and monsters from hell arrive on Earth, sent by Lucifer to find his precious son, the Avengers will do whatever it takes to find him and keep Earth safe and return him to his smothering daddy.
