An old friend of Andy's who is on the space station calls her because she has a medical problem. It seems she needs surgery but can't get off the station. So she has to try to coach the doctor on the station who is a vet on how to do it. So NASA techs come to the hospital so they set a link with them. Lu as a patient who has symptoms she can't figure out is causing it. And another patient wants to have a mastectomy because she fears of having breast cancer.
