Captain America: The Winter Soldier
Fury's close friend and S.H.I.E.L.D. agent Maria Hill (Cobie Smulders) takes Steve, Sam, and Natasha to a safehouse where Fury is still alive, having faked his death to go undercover. Fury gives them controller chips that they can use to disable the Helicarriers before Hydra can use them. Steve tells Fury that he plans to completely destroy S.H.I.E.L.D. to stop Hydra from ever forming again. They all go to S.H.I.E.L.D. headquarters, where Steve tells everyone the truth about Hydra and their plan and Natasha leaks Hydra's files to the public. Fury fights and kills Pierce for his betrayal. Meanwhile, Steve and Sam are able to get inside two of the three Helicarriers and disable them with the controller chips. On the third Helicarrier, Bucky appears as the Winter Soldier and tries to stop Steve, but Steve inserts the final controller chip and foils Hydra's plan. Steve refuses to fight Bucky and tries to make him remember that he's his best friend. At first, Bucky resists and attacks Steve, but soon realizes the truth. As Steve falls into the Potomac River, Bucky saves him from drowning and disappears.
