 McMurphy is on a short fuse when an army psychiatrist comes to China Beach to gather material for a research project about stress on non-combatants, and irritates her with the matter in which he encourages some of the grunts to go back out into the jungle. But it proves to be wrapped up in her coming to terms with Natch s fate which is causing her insomnia and her increased alcoholism. Meanwhile, Frankie finds love with a black platoon leader who turns out to be just another womanizer. Beckett thinks of proposing to Mai, and K.C. returns to China Beach from Cherry s funeral.
