You will need to hire a criminal defense attorney to review the district court file and see if a motion to set aside the plea/conviction/judgment is a viable option. It is worth the investment.
I am trying to give you a general answer to your question. We do not have an attorney-client relationship by this response on the avvo website. I have not been retained to represent you. I am licensed to practice law in Kentucky and in federal court in this state and the Southern District of Indiana. You need to seek legal advice from an attorney licensed to practice in your area..
