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.

Wayloo Marie's digging results in a medal ceremony for Boonie and an unwelcome investigation into his lost jungle patrol. McMurphy sees Dodger again as he prepares to go back into action. Frankie befriends a captured deserter.

Dodger tries to reintegrate his life as a civilian but finds himself drifting as he tries to make sense of his experiences in Vietnam.

In November 1966, fairly new guys Colleen McMurphy and Dr. Richard find themselves learning the ropes when they arrive at China Beach.
