 The Doctor is stolen from Voyager by an alien who sells him and his mobile emitter to a hospital on densely-populated planet. He is activated in a cramped room filled with sick people and is made to treat them using only very basic equipment. When the administrators of the facility realise how skilled the Doctor is, they move him to another area of the hospital to treat more deserving patients. The Doctor is appalled to learn that the medical care that people are given is linked to their status in society and hatches a plan to make things a little less discriminatory.
