Captain America: The Winter Soldier
Not knowing who to trust anymore, Steve and Natasha hide in Sam Wilson's house. Sam tells them that he has a "Falcon" wingpack that he used during his time in the military, and they decide to recruit Sam to stop Hydra with them. They kidnap Hydra mole Jasper Sitwell (Maximiliano Hernandez) and force him to tell them Hydra's true plan: to hijack Project Insight by using an algorithm made by Zola to find threats to Hydra, and use the Helicarriers to kill them even before they commit any crimes. The Winter Soldier and his men return and ambush the group, killing Sitwell. After a fight, Steve unmasks the Winter Soldier to reveal James "Bucky" Barnes (Sebastian Stan), Steve's best friend who was thought killed in the 1940s, but was secretly kidnapped by Hydra and brainwashed to follow their orders.
