It's November 1967 and nurse Colleen McMurphy faces the last week of her tour of duty in Vietnam, dealing as usual with the dying boys, primitive conditions, and the sexual pressure from pilot Natch Austin. USO singers Georgia Lee and Laurette Barber arrive to entertain the troops in the base's new R&R center. Brand new Red Cross volunteer Cherry White also arrives, determined to find her brother, a marine no one can locate.

McMurphy decides that she can't leave China Beach even though she is eligible to go home. Cherry and Laurette arrive- Cherry to look for her brother whom her family lost contact with and Laurette as a USO back up singer who gets promoted to lead when the lead singer can't cope with the war.

McMurphy and K.C. are kidnapped by the Viet Cong and taken underground into a warren of tunnels, where their captors expect McMurphy to operate on their wounded leader.

The wounded Cambodian POW befriended by McMurphy is taken away by the South Vietnamese for interrogation as the photographer Cat pursues the story of his defection and a new commander arrives to take over the base, leaving Lila and K.C. unsure of their positions.

McMurphy finds herself caught up in a triangle affair with Dr. Bernard and Vinnie; Holly tells Boonie how she feels about him; and Lila copes with the disappointment of losing command of China Beach to Otis.

K.C. feels responsible for the death of a Vietnamese prostitute she sent out and takes things into her own hands when Otis refuses to investigate the matter.
