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.
