It's an unusually hectic night at the hospital, with the doctors busy juggling patients and Dr. Cox barking orders at everyone. Dr. Cox is more gruff than usual because he is trying to accomplish the equivalent of a pitcher's "no hitter" - having no patients die during his twelve-hour shift. Meanwhile, hospital social worker Alex Hayden, slipped in the hospital, knocking herself unconscious. Hoping to prevent a lawsuit, Dr. Kelso has J.D. meet with her as she is getting an M.R.I. to see if she sustained any head injuries. Alex quickly perks up when she meets J.D. His wit and good looks are definitely winning her over, but since her face is obscured by the machine, J.D. can't see her (but she can see him). During the procedure, the machine jams, trapping Alex in the M.R.I machine. J.D. runs to get help, but quickly returns to keep Alex company. Just as Alex emerges from the M.R.I. machine, J.D. stops her before he can see her face. He decides to take a leap of faith in asking her out before he has a chance to see what she looks like.
