A mysterious fugitive, a hijacked airplane and a daring mid-air escape. This is the extraordinary, real-life tale of one of the greatest unsolved heists in American history and a case that has taunted the FBI for decades. This documentary brings the stories of the four possible suspects to life through candid testimony, archive footage and stylised drama. Each account is gripping and highly plausible. But who is telling the truth, who is lying and, ultimately, who is DB Cooper?
