I'm looking for a specific fic where Cap and Hawkeye are on a mission where their helicopter/plane crashes and Cap is captured. The fic switched perspectives then from the Avengers trying to figure out how to infiltrate the compound to get Cap out, and Cap's time as a prisoner. Specific things I remember:
- Cap tries to escape and is locked in a freezer as punishment.
- There's an auction to bid on Captain America, which the Avengers infiltrate.
- Bruce and Natasha go undercover (Bruce as a bidder), with his interest made credible because of his experience with the Super Soldier serum.
- I believe it was posted on ff.net.
