The story begins where it left off. Not at the end of the previous Avengers, mind you—that would be too straightforward—but at the end of last year’s Captain America: The Winter Soldier. Having located the wooded alpine lair of Hydra commander Baron von Strucker(Thomas Kretschmann), the Avengers proceed to assault it. Therein they find both Loki’s scepter and a pair of decidedly unfriendly super-powered twins, Pietro and Wanda Maximoff, played by Aaron Taylor-Johnson and Elizabeth Olsen, respectively.(The super-monikers are never used but, yes, these are Quicksilver and the Scarlet Witch.)
