Be warned, there will be spoilers throughout the rest of this story, so read on at your own risk. If you don't want to know how Avengers: Age of Ultron begins, stop reading now. Also note, while this info comes from solid sourcesl, none of it has been confirmed by Disney or Marvel at this time.

Avengers: Age of Ultron starts directly after the end credits scene in Captain America: The Winter Soldier, where Baron Von Strucker (Thomas Kretschmann) is seen holding Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen) captive. The Avengers attack Baron Von Strucker's rogue Hydra outpost to retrieve Loki's staff, Chitauri weapons and the corpse of a leviathan. As the Avengers move in, both Quicksilver and Scarlet Witch fight alongside Von Strucker, with Scarlet Witch casting a hex on Hulk that makes him think the leviathan is still alive. This causes plenty of rage-fueled smashing from the Green Goliath.

Eventually, the Avengers emerge victorious and head back to the Avengers Tower in New York to throw a big party, where each Avengers takes their turn trying to pick up Thor's hammer Mjolnir. When Tony Stark (Robert Downey Jr.) tries to pick up the hammer, the arm of his armor falls off. Captain America (Chris Evans) is able to slightly move the hammer, but he still can't pick it up, although this scene may change since, in the comics, Cap can actually wield Mjolnir.

Last week, Mark Ruffalo revealed that not only does Hulk have a bigger role in the sequel, but it is "more complex" with "more layers and a bit more arc." During the party scene, it is revealed that Bruce Banner and Natasha Romanoff (Scarlett Johansson) now have romantic feelings for one another, and we also learn that Thor (Chris Hemsworth) and Jane Foster (Natalie Portman) have broken up. Thor is seen at the bar, watching Jane with Richard, Chris O'Dowd's character from Thor: The Dark World.

These scenes encompass the first 15 to 20 minues of the movie, with the Avengers cleaning up the last of the Hydra cells before going home to party. Of course, this could all change with rewrites as production continues, and none of this has been confirmed by Marvel, but the site did indicate that Marvel will likely release the following information over the net few months in the form of teasers and other promotional material.
