The Falcon and the Winter Soldier - My Own Version

This is my first story and wanted to put my story out there as I hope to be a good author soon. The story is about Sam and Bucky adjusting to a normal life with old man Steve in their little home. They try to make things work and Sam adjusts to being the new Captain America. When Shield calls for them to help with a mission, Sam and Bucky prepare without Steve by their corner. They seem confident but their new boss Ross doesn't want Sam as Captain, but rather the new guy John Walker because Ross thinks John's features are close to Steve Rogers. Walker decides to do the mission alone, while Sam and Bucky go to prove Shield wrong with a little help from Sharon and one of Shield's new members America Chavez . They go to stop the virus that Zemo tries to unleash, but can the Falcon and Winter Soldier work and get this mission accomplished.
