Twenty-eight years after the Korean War, former M*A*S*H surgeon ""Trapper"" John McIntyre, now Chief of Surgery at San Francisco Memorial Hospital, is faced with a younger copy of himself - Vietnam vet Dr. ""Gonzo"" Gates.

Trapper and Gonzo deal with a deranged Vietnam vet, while Stanley tries to save on taxes by incorporating himself.

When an employee from a local nuclear power plant is admitted to SFM with signs of radiation poisoning, Gonzo cannot understand why it appears that nothing is being done to protect other workers from exposure.

A persistent swain of his ex-wife, Melanie, causes both professional and romantic turmoil for Trapper. Stanley is determined to get rid of the ""Titanic"".

An injured boy is torn between the mother he ran away from and the man he considers to be his father. A grateful sheik gives Gonzo a present he can't refuse - his daughter.

A brilliant improvisation saves a life but causes problems for Trapper and Riverside.

There is a bomb somewhere in the hospital set to go off at midnight. The bomb squad can't find it, and the man who planted it is dying from bullet wounds. Can Trapper and Gonzo save his life in time to save San Francisco Memorial?

A former patient who recovered from terminal cancer using a holistic approach he devised has written a book and is looking for converts. He convinces a lupus patient to stop all medical treatment, and nearly allows her to die before accepting that she needs help he cannot give her.

Gonzo takes a leave from the hospital to supervise a very rich young woman with a rare medical condition, and is charged with sexual misconduct when he rejects her advances. Trapper looks for a new scrub nurse to replace Starch.

The mother of a little girl who needs heart surgery refuses to let Gonzo operate because of sexual misconduct charges pending against him. Ernie agrees to take the job as Trapper's scrub nurse.

Hub Wendover arrives at San Francisco Memorial Hospital for treatment for his leg and to be close to his son, Gonzo. Trapper operates on Hub finding his body riddled with cancer. Gonzo and Hub have some issues to deal with. Gonzo can't help but love the Father that supposedly walked out when he was four years old.

Stanley wants to upgrade the hospital's image, and puts forth a talented staff surgeon as a ""typical"" SFM doctor - until he learns that the man is a local Ku Klux Klan leader.
