Danny refuses to leave and the 3 thugs won't let the soldiers force Danny out. Later, Anderson and Team Viking are trying to find a road that is part of the Ho Chi Minh trail. When they find the road they return to the base where everyone knows about Danny. Brewster tells Goldman to solve the problem and Goldman insists upon talking about the massacre.

Anderson (under pressure from Goldman) organizes a commando raid and goes into Cholon to spring Purcell -- who then is forced to go through cold-turkey withdrawal. Brewster is ordered to shut up about the Phu An massacre.
