Such Great Siege (слэш)

In the aftermath of defying his country to save his best friend, Steve Rogers agreed to a plea bargain that would grant his friends immunity but send him to prison. That was two years ago.
Bucky had a plan for when Steve finally was released from prison: a quiet house and a big bed, maybe a dog. None of his plans included Steve agreeing to sacrifice himself to save the very people that had stripped him of his title and took away his freedom. But old enemies have a way of coming back.
