It turned out that this friend put a CD recording the whole process of a powerful person murdering a congressman into Dean's bag! Poor Dean was closely monitored by the bad apples in the NSA without knowing it, and was subjected to various pressures. He was even sued for murdering his ex-girlfriend Rachel for no reason. Dean had no choice but to flee alone and track down the real murderer behind the scenes.
