Nate finds himself in a pickup with a man he can't stand. His father wants to reconnect, and he wants Nate to really understand him. Larry Huffman has chosen to make this happen by taking his son into his own past, which has the Vietnam War as its centrepiece.
As the two struggle their way through the jungle of the Ashau Valley, the old man relives the horror of the battle that changed him forever, and Nate undergoes changes of his own -- and they experience something that goes far beyond what either of them expected.
