The episode opens in surgery. Hawkeye and Houlihan operate on a patient and the former insults Frank. However, Hawkeye's patient fails to improve after surgery. Hawkeye becomes overly concerned with the case, to the point of punching Frank over comments at lunch, falling asleep in Post-Op, snapping at Trapper for playing poker too loudly, and moving out of the Swamp to the supply tent. While Hawkeye retreats to the Supply Tent to reflect on the case, he is interrupted by his date (whom he turns away), Trapper (whom he turns away as well), two other soldiers, and Henry. Henry implies that Hawkeye is concerned more about his ego than about his patient. Hawkeye returns with a glib remark about Henry's intelligence, which ultimately insults Henry and allows Hawkeye some peace and quiet. While pondering the case outside the Supply Tent, Hawkeye encounters Major Houlihan and she theorizes that they made a mistake in the surgery, eliciting extreme doubt from Hawkeye, who in turn insults her. During the night, Hawkeye has an epiphany and reopens the patient to find a small piece of shrapnel embedded in the patient's small intestine, at which point Frank states, "Anybody could have missed that."
