Enter Federal Prosecutor Philip St.John, he suggests avoiding a normal court trial and charges Locke with mail fraud, based on his claims for payment from his insurance company, which allows him to bring him before a Federal Grand Jury. When the â€˜trial' starts Quincy discovers that there a literally no rules in a grand jury and the defendant can have no representation to help in defending himself. Quincy decides that he is not going to stand for this and tries to help his friend out.
