John Dorian, "J.D." to friends, is a boyishly handsome, self-deprecatingly funny, likeable guy who would be confident if he only realized his assets. Four years of medical school have prepared J.D. for his first day as an intern at Sacred Heart Hospital - but he has his doubts.

The three interns are each assigned patients with various illnesses. Statistically speaking, one of the three is going to die. J.D.'s patient is 86 year old Mrs. Tanner, who is in renal failure. 20 year old David Morrison is Turk's hernia patient and Elliot's patient Mrs. Guerrero only speaks Spanish and might have lupus.

J.D. points out what seems to be a technical mistake to Dr. Kelso, but it was really an attempt of Dr. Cox to save a woman without insurance using a dead guy's insurance.

Meanwhile, the Janitor intimidates J.D., Elliot discovers the healing powers of her boobs and Turk gives Carla a pen he thought he took from the Lost and Found box.

J.D. has finally earned the spot as brightest student, but he's got competition: Nick Murdoch, who seems to be nicer, friendlier and has a better butt than him. But even J.D. can't hate the guy.
