Morrison treats the obnoxious bank bomber; Mr. MacAllister arrives to find his wife in a coma; Dr. Craig holds a news conference and badgers a patient into a surgical consent; and Dr. Samuels tries to teach Dr. Beale how to swim.

Dr. Westphall risks his job by creating an isolation floor to stem the spread of the suspected Legionnaire's Disease (and the PR fiasco causes administrator Cummings to fall on his sword to save the hospital); Dr. Beale learns that Tweety got pregnant while in the hospital; Fiscus is assaulted in the E.R.; and Dr. Craig decides to sell his car.

The search continues for the source of the Legionnaire's Disease; Cavanero befriends a young woman facing a hysterectomy; Tweety makes a decision about her future; and Ellen Craig deals with the elusive Dr. Barnum.
