A brain-aneurysm patient spirals into dementia and comes to believe Christina is his wife, and Christina then grows attached to him. Meanwhile, Kelly tangles with an ornery and demanding patient; and Bobbie mulls over starting a romance with a handsome paramedic.

Christina races to save a woman and her child in the wake of a car accident. But in a bizarre turn of events, the two victims develop a sudden paralysis seemingly unrelated to their accident injuries. Meanwhile, a cancer patient takes a surprising turn for the better; Kelly gets lost in the labyrinthine hospital; and a conniving Camille pushes to attend a class trip.
