Captain America: The Winter Soldier
Pierce asks Steve to tell him what was on the hard drive Fury gave him, but Steve refuses. Angry, Pierce tells S.H.I.E.L.D. that Captain America is an enemy and orders them to hunt him down. Now on the run from S.T.R.I.K.E., Steve meets Natasha and they work together to decode Fury's hard drive. The drive leads them to the army base in New Jersey where Steve was trained in the 1940s. The two of them find a secret bunker with a supercomputer that contains the consciousness of scientist Arnim Zola (Toby Jones), who was thought dead in the 20th century. Zola tells them that he rebuilt the evil organization Hydra from within S.H.I.E.L.D. so they could cause chaos, and that S.H.I.E.L.D. is filled with Hydra double agents who use the Winter Soldier as their main assassin. Steve and Natasha escape the bunker before it's destroyed by a S.H.I.E.L.D. missile. They quickly figure out that Pierce is actually Hydra's leader while pretending to be one of the leaders of S.H.I.E.L.D.
