Marvel Studios has released the official film synopsis for the upcoming “Avengers: Age of Ultron.”

In the second installment, Tony Stark is attempting to keep the peace through a new program with Ultron appears and throws of the entire plan.

Robert Downey Jr. recently explained to Entertainment Weekly his character wanted to create the program in order to give the Avengers a break from sacrificing their lives in order to keep the world safe.

"What you said about abdication is apt, but I think it's also about recognizing limitations," Downey said.

"The downside of self-sacrifice is that if you make it back, you've been out there on the spit and you've been turned a couple times and you feel a little burned and traumatized."
