The flight of a butterfly illustrates the delicate balance between the powers of medicine and nature. -- In a unique episode, the path of a butterfly is the deciding factor in the fate of the young doctors. At the beginning, a butterfly landing on a woman's breast sets off a chain of events ultimately resulting in the death of J.D. and Turk's patient, leaving them to wonder what they could have done to change the outcome of their day.

Will this be enough to change the fate of their patients?
