Fan Casting Captain America vs The Winter Soldier

The movie opens as Steve Rogers meets with Nick Fury and Agent Clint Barton. Nick explains to Steve that over the 70 years he was in the ice and the 5 he's been active, Hydra has started to show back up as he already knows, and now a terrorist called the Winter Soldier has been attacking S.H.I.E.L.D left and right for the last 4 months. They attribute his strength and speed to the same serum that gave Steve his powers. Nick introduces Steve to Clint, who will be helping him on this mission to locate the Winter Soldier. The two track the Soldier to an abandoned warehouse where Steve meets the soldier face to face. Steve realizes this soldier is far too strong and tries to leave but the Soldier gets a hold of Steve's shield and takes it. Steve and Clint arrive back where Clint gives Nick a hard-drive with blueprints for a particle accelerator on it belonging to Hydra. Nick recognizes the logo on the files as the Intelligencia branding. Steve and Clint go back out and eventually use the drive to track down the Hydra outpost where the blueprints were supposed to be delivered. Steve confronts the Soldier and finally realizes it, it's Bucky Barnes, his old war buddy who died saving him. The two fight while S.H.I.E.L.D and starts seizing control of the outpost. They realize they have more copies of the blueprints. Steve gets his shield back but is taken down. Bucky looks at him carefully and surprisingly spares him before leaving. Steve gets up and Clint tells him they'll find him.
