Wrong Man 

A young girl is murdered with a single bullet through her skull. A homeless man is arrested, and as the evidence against him stacks up, everyone thinks he’s guilty — except lawyer Jason Kolarich. Jason can’t resist the urge to dig deeper, and begins to uncover a much darker reason for her death. What he finds will crack the case wide open. An army is training for a war against the government. Everyone is going to pay for what they did.
