First things first: Spoiler Alert. We will discuss the whole movie, including plot twists and what-the-fuck-moments, so if you haven’t watched the movie yet… what are you waiting for?!
It starts out with an action scene with all the Avengers fighting Hydra together, looking for Loki’s staff. The Maximoff twins make their first appearance as Scarlet Witch (Elizabeth Olsen) and Quicksilver (Aaron Taylor-Johnson), messing stuff up, but the Avengers retrieve the staff, and we see Natasha helping the Hulk transform back into Bruce Banner. Tony Stark, wanting to create “a suit of armor around the world”, uses the staff to try and create artificial intelligence, calling it Ultron, but fails. There’s a party – where everyone tries to lift Thor’s hammer but fails – which is crashed by Ultron, who, after all, was created. Well, big surprise, Ultron is not a big fan of humanity and wants to destroy it, and we have a movie.
