The VC are mauling the American soldiers through their use of the underground tunnels. On their latest trip into the bush, Anderson and the men provide a blocking force, only the Gooks being driven toward them disappear down into the tunnels... and Goldman and Anderson end up firing on Americans -- thinking they are VC coming toward them. The team ends up in a village but again gets attacked as the VC pop up out the tunnels and then back into them after the attack. Taylor is captured during this fighting -- having been wounded. Taylor ends up being befriended by a VC Doc who has no interest in fighting -- only in returning home alive. On the surface, Anderson and Goldman go into the tunnels, only to end up entombed by a cave-in.

Two sappers make their way into Firebase Ladybird without being detected, but Percell sees the third one, killing him. The other two manage to set off their explosives before they can be stopped. The next morning, Capt. Wallace orders Anderson and Goldman to have their men police up the dead bodies.. Anderson complains his men are beat, but Wallace isn't concerned. Percell is upset both over a friend's dying and having received a ""Dear John"" letter. Goldman, meantime, runs into an old friend: Lt. Nikki Raines, and promises to meet her later. Goldman, Anderson and the squad go out to destroy a bridge, which they blow up. Percell, in the midst of chasing a running VC, accidentally kills an 8-year-old. Percell is devistated over the incident.
