Hindsight is the 10th episode of the 9th season of "E.R."
The past 24 hours of Luka's day play in reverse after he gets into a car accident with med student Erin Harkins after working hungover the day after a staff Christmas party which results in the misdiagnosis of a patient that ends up brain dead.
ER' REVERSES FORM IN UNIQUE CHRISTMAS EPISODE AS EVENTS UNFOLD FROM END-TO-BEGINNING: In a form-breaking episode, events just before Christmas are traced in reverse chronological order as a hungover Dr. Kovac's (Goran Visnjic) troubled life lurches closer to tragedy when his car accidentally hits another auto on icy roads, endangering his passenger, young resident Harkins (guest star Leslie Bibb, "Popular").
While on duty, Kovac struggles to help a sickly young man (guest star Michael Ealy, "Barbershop") fight for his life.
In addition, Abby (Maura Tierney) and the emergency room staff attend to a pair of belligerent elves and a young female hockey player (guest star Brittney Lee Harvey) with a head wound.
Noah Wyle, Laura Innes, Ming-Na, Sherry Stringfield, Sharif Atkins and Mekhi Phifer also star. TV-14
