Having received some warning of the upcoming Tet Offensive (In Angel of Mercy), Bravo Co. is still unprepared for what happens to them after they are transferred to Tan Son Nhut Base outside of Saigon. Zeke and Goldman catch up with one of their men in an opium parlor and have a run-in with some Vietnamese thugs. The situation is basically under control until a female wire service correspondent -- Alex Devlin -- butts in. Alex explains that she was following up on a story lead. Lt. McKay is introduced as a chopper pilot who will be shuttling Bravo Co. As they prepare to leave on a mission, Zeke opens a letter from his ex-wife who claims she will soon arrive in Saigon to see him. The company is landed in a hot-LZ and only gets saved from sure disaster when Lt. McKay uses his helicopter to fire machine guns at the hostile position.

Goldman is ordered to have Alex pull her story about the soldier who died in the opium parlor and Zeke runs into Stacy Bridger -- rescuing her from some Vietnamese punks. He takes her back to the hotel where Zeke ends up trying to save a suicidal marine deserter. The deserter has sold information to the VC and ends up killing himself. Meanwhile McKay sends Goldman on a ""snipe"" hunt so that he can be alone with Alex, and inadvertently exposes Goldman to serious danger.

While out on a patrol, Anderson and Goldman observe some VC transporting an American prisoner and photograph him before leaving the area. Although they are badly outnumbered, Ruiz stupidly goes back down the trail after a necklace he dropped, tipping their position and getting a man killed. Alex drops by to see Goldman. Zeke goes to the hospital to try to straighten out some records and ends up saving the life of psychiatrist Jennifer Seymour from a homicidally insane LURP. An explosion in the latrine sets of Major Darling, while Anderson suggests that it might not be VC but an American solider who planted the grenade.

It is obvious that Goldman and his men have been used by Doyle to provide himself with an escort out of the bush. They get ambushed on the way out. They get most of the rifles back, but Zeke and Myron wonder why they were ambushed by Montagnards, a group known for their loyalty to Americans. Goldman decides to investigate Doyle and enlists Alex's help. Doyle learns he is being investigated and leans on Zeke to get the lieutenant to stop.

Beller tells command that his men need rest or they are going to snap but Brewster insists they must go out. Meanwhile everyone is happy to see Anderson return, except for the ever-depressed Percell. Goldman spends some time with Beller. Percell is going over the edge fast and no one knows that he has started to use drugs. Anderson discovers that Brewster is married to a Vietnamese girl and they have a child. The next day, on their mission, Percell (drugged up) starts to panic. Beller's unit creates a My Lai-type of massacre in the field and that sends Percell off the deep end and straight into the waiting arms of heroin dealers.
