The first official plot synopsis for next summer's Avengers sequel has arrived, alluding to some critical plot points that suggest Tony Stark (aka Iron Man, aka Robert Downey Jr.) is the one who unintentionally stirs up trouble, landing his superhero friends in what may be the biggest pickle the world has ever faced. 

Check it out below:

"Marvel Studios presents Avengers: Age of Ultron, the epic follow-up to the biggest Super Hero movie of all time. When Tony Stark tries to jumpstart a dormant peacekeeping program, things go awry and Earth’s Mightiest Heroes, including Iron Man, Captain America, Thor, The Incredible Hulk, Black Widow and Hawkeye, are put to the ultimate test as the fate of the planet hangs in the balance. As the villainous Ultron emerges, it is up to The Avengers to stop him from enacting his terrible plans, and soon uneasy alliances and unexpected action pave the way for an epic and unique global adventure.

Marvel’s Avengers: Age of Ultron stars Robert Downey Jr., who returns as Iron Man, along with Chris Evans as Captain America, Chris Hemsworth as Thor and Mark Ruffalo as The Hulk. Together with Scarlett Johansson as Black Widow and Jeremy Renner as Hawkeye, and with the additional support of Samuel L. Jackson as Nick Fury and Cobie Smulders as Agent Maria Hill, the team must reassemble to defeat James Spader as Ultron, a terrifying technological villain hell-bent on human extinction. Along the way, they confront two mysterious and powerful newcomers, Wanda Maximoff, played by Elizabeth Olsen, and Pietro Maximoff, played by Aaron Taylor-Johnson, and meet an old friend in a new form when Paul Bettany becomes Vision."

Based on the little bits and pieces we already know about the film, it's Stark who inadvertently creates the megasupervillain Ultron in his attempt to invent a weapon that would make it so the Avengers didn't have to exist. Naturally, that weapon -- voiced and performed by scenery-chewing champ James Spader -- is what ultimately reunites them in a quest to prevent it from wiping out humanity. Color us ready to watch this movie yesterday!

So when do we see a trailer? Well, Robert Downey Jr. may have just teased it via Twitter. What do you think he's talking about in the below tweet?
