It's daylight in the jungle. Writing on the screen tells us it's New Year's Day, 1968, as does Taylor's voice.
He gives us an update about what's been happening over the last few months: lots of small skirmishes, lots of bombs dropped, followed by lots of walks through the jungle.
Taylor is on point (i.e. in the lead). He hears something, pauses, and turns back to look at Barnes.
Barnes pauses, comes closer, and then says "Bunker." Taylor asks him where.
The camera shifts to an angle inside the bunker, looking out. The guys cautiously approach and fan out, examining the area near the bunker.
Clothes are hanging, and fires are still smoking so the enemy has only recently departed.
Elias climbs in, and then drops down a few feet into a tunnel to investigate further. Soon, he's wading through water before ending up in a dimly let bedroom, complete with a bed, sheets, and… a dead body? Yep. Elias keeps going.
Meanwhile up above, the guys are poking around, on alert. Tensions are high.
Elias stumbles on a command room of some kind, sees an enemy soldier, and shoots him with his pistol.
Sal and another guy are checking out some documents they've found in one of the huts nearby.
The camera pans away for a few minutes to focus on the other guys when suddenly an explosion erupts: one of the guys looking at the maps emerges, and quickly falls over, dead.
Wolfe gets on the radio and calls for backup. Elias comes out, tells them to get out of there. There are booby-traps all over, and they need engineers.
Wolfe says they're on their way, but in the meantime they need to head out. NVA soldiers have been spotted nearby.
Barnes is sitting by himself, smoking. He's in a strange mood. Taylor is staring at him. Barnes stares back, and says nothing.
The troops get ready to move out, but can't find Manny (Corky Ford). Elias and a few goes go looking for him. All that can be heard are the sounds of the jungle.
