Learning the truth

When Tony goes missing after Siberia and ends up in the hands of Hydra, will the 'team' do anything to find him? When they cross paths with an on-the-run scientist, what information can they learn about Hydra's new weapon? Will they learn things that they didn't want to know?
(First ever story, sorry it's a crappy summary. I do not own marvel or Tony would still be alive. Ye, please read.)
