When an ex-horseman makes a deal with satan, a diverse army of supernatural beings are summoned into the realm and The Four Horsemen are called to take them down.

When an ex-horseman (Loki) makes a deal with Satan (leader of Chitauri), a diverse army of supernatural beings (The Chitauri) are summoned into the realm (Earth) and The Four Horseman (The Avengers) are called to take them down.

It's a low concept idea and it's not very interesting. The phrasing is poor and it's written like an amateur with no critical thinking.

Isn't this just the Avengers?
