Synopsis by Hal Erickson
In the opening episode of M*A*S*H's fifth season, the 4077th prepares to pull up stakes and move out in the face of a rumored Chinese attack. Unfortunately, Hawkeye is in the middle of a crucial operation and cannot move his patient. B.J. (Mike Farrell) and Margaret (Loretta Swit) volunteer to stay behind and assist Hawkeye--and, hopefully, stay alive in the process. Originally telecast as a 60-minute "special", "Bug Out" has since been reedited as two half-hour episodes for syndication purposes.
