Captain America: The Winter Soldier

Steve Rogers is coming to grips with living in modern America after being frozen in ice for 50 years. A new threat against S.H.I.E.L.D. arises called "The Winter Soldier". While the origins of the Winter Soldier are unknown, the threat against S.H.I.E.L.D. from the Hydra organization is. Especially after it compromises Nick Fury and Agent Romanoff, leaving them betrayed and left for dead, and their S.H.I.E.L.D. status revoked, marking them as traitors to the organization. Now racing against time with very little resources available at his disposal, Captain America launches an investigation into S.H.I.E.L.D.'s origins and that has him returning to the very Army base where he once underwent basic training nearly 100 years ago. What he, Romanoff and Jack discover there leads to a very startling development with S.H.I.E.L.D., a top secret project called "Operation Insight", and the launch of the next generation of Helicarrier. Can they stop it before it's too late?
