In the conclusion of the series' fifth-season opener, the 4077th has moved out, leaving Hawkeye (Alan Alda) behind to complete an extremely delicate operation. With a reported advance of Chinese troops in the offing, B.J. (Mike Farrell) and Margaret (Loretta Swit) volunteer to stay behind as Hawkeye's assistants--and as moral support when the shooting starts. The question now is: Will the rest of the M*A*S*H unit return in one piece? Originally telecast as a 60-minute "special," "Bug Out" has since been reedited as two half-hour episodes for syndication purposes.
