The plot of the fourth film will take place on earth as the heroes prepare for one final assault against the Mad Titan of the universe. Thanos will collect all of the Infinity Stones with the help of his children, The Black Order.

Time traveling Avengers?
The new behind-the-scenes photos of the fourth "Avengers" movie teased that Iron Man, Hulk, and Ant-Man traveled back in time during the Battle of New York. The three heroes stumble upon Steve Rogers who is wearing his original "Avengers" movie uniform.

While the purpose of there visit is unknown, it seems that whatever they are doing will affect the outcome of the future timeline. The Chitauri Invasion marks the formation of the original team as they stop Loki from conquering earth.
