When there's a robbery at the Federal Reserve, the FBI finds D.B. Cooper money. They follow a lead to an armored car driver, killed before they arrive. His Uncle, Roy Till, becomes the lead suspect in a 1971 hijacking. Our guys call on Roger Bloom (Henry Winkler) for his expertise. Bloom tells them that D.B. Cooper asked for two chutes, and they found the body of Eddie Dwyer in a tree. Theory was that Cooper stabbed him and threw him off the plane as a decoy. Now Dwyer's son, Teddy Angell, is after Till for revenge.
