North Korea prevents a kidney donor from traveling to the U.S., which means Trapper (Pernell Roberts) must go to Seoul, where he encounters his wartime flame.

Libby (Lorna Luft) is devastated to learn that an old flame is gay and an AIDS victim.

Administrator Hackett (Janis Paige) refuses to hire a flashy medevac doctor. TJ. and Gonzo can't understand her reluctance until one day a secret from the man's past is revealed. The seat-of-the-pants operator of a helicopter medical-evacuation service lands with a patient in the hospital parking lot.

Trapper keeps watch on the artificial-heart recipient, while Gonzo tries to convince Fran that his love for her doesn't come from pity. Trapper's artificial heart recipient (Hoyt Axton) suffers from complications; Dr. Brennan learns she has multiple sclerosis and rejects Gonzo's support.

Seventh season starts picking up scalpels again for a new round of aches, pains, romances, jealousies and assorted other problems that flood the corridors of San Francisco Memorial. In the first of a two-part episode, T.J. tackles his first artificial heart transplant. And who's that lying flat on his back awaiting the surgery? Good ol' Hoyt Axton, in a guest role. A cardiac patient who cannot risk the wait for a human heart tries his only chance, an artificial pump. As Trapper John (Pernell Roberts) prepares for his first artificial heart transplant, Gonzo (Gregory Harrison) helps him out with a personal matter, playing host to his pushy Aunt Mo (Pat Carroll). In the process he meets a beautiful doctor, Fran Brennan (Andrea Marcovicci). On part one of the season premiere of Trapper John, M.D.
