Told in reverse chronology, this episode details the 24 hours leading to the disastrous misdiagnosis that may spell the end of Kovac's (Goran Visnjic) medical career. The whole story stems from a Christmas party at the home of Dr. Susan Lewis (Sherry Stringfield), where an apparently inebriated Kovac makes a play for med student Erin Harkins (Leslie Bibb). Things come to a head in a car accident which leaves one passenger seriously injured and another with apparently irreversible brain damage. ~ Hal Erickson, Rovi
