Synopsis by Hal Erickson
Season Four of M*A*S*H (now moved to Friday evenings) begins with the ever-irritating Maj. Frank Burns (Larry Linville) assuming command of the 4077th after the death of easygoing Col. Henry Blake. Returning from an R-and-R session, Hawkeye (Alan Alda) discovers that his old buddy Trapper John (Wayne Rogers) has been shipped out without so much as a goodbye. The sullen Hawkeye is then sent Kimpo to pick up Trapper's clean-cut replacement, B.J. Hunnicut (Mike Farrell in his first series appearance), whose spotless record leads Frank and Hot Lips (Loretta Swit) to the premature conclusion that, at long last, the joyful slovenliness of the 4077th will be replaced by traditional military spit-and-polish. The first of the series' 60-minute "special" episodes, Welcome to Korea has since been divided into two half-hour episodes for syndication.
