About Lt. Rollins[]
Klinger is brought in to face a courts martial, charged with being part of a black market ring when a Polaroid land camera for the officers that Hawkeye and B.J. received as a gift from the grateful father of a patient of theirs - which the prosecution alleges was acquired by Klinger from the ring. The prosecuting attorney, Lt. Rollins, who looks so youthful, that it's as if he's fresh out of law school and recently passed his bar exam, manages to drag damaging testimony for Klinger, while making a babbling fool out of Charles, who tries to defend him.
Colonel Drake (Peter Hobbs), the presiding judge, after hearing both sides, is about to render his decision, and the case starts to look really bad for Klinger.
But, both Hawkeye and B.J. come to save the day, having returned to the trial after being able to set a trap for the real culprit, a crooked M.P. while they were in surgery, as they cause Rollins's case against Klinger to fall flat, as he, instead of Charles, has egg all over his face as the Colonel Drake exonerates Klinger.
