In the 12th season premiere, Sam and Kovac report to the police that her diabetic son, Alex (recurring guest star DOMINIC JANES), is missing and is possibly trying to find his father. The boy mistakenly thinks his dad is in Colorado, but the man is actually incarcerated. Unfortunately, Alex left without his insulin. And Neela, Ray and Abby struggle with their first shifts in charge of the new interns. Also available on VUDU

On Carter's final shift at County General, four new interns begin their medical careers. After completing their rounds, Carter, Kovac and most of the emergency room staff attend Carter's surprise going-away party. Ray leaves to go to another event where the revelry is interrupted by a disaster that truly tests his triage abilities. The casualties are taken immediately to the hospital where a skeleton staff, headed by Abby and Neela, must overcome their lack of experience and treat the patients. Meanwhile, Pratt finally gets the courage to confront his father, Charlie (recurring guest star DANNY GLOVER - 'Lethal Weapon' films, 'The Royal Tenenbaums'). And Sam and Kovac search for Sam's son after he runs away in search of his imprisoned father. Also available on iTunes

Neela helps treat two Amish teens who were in a car crash. Sam argues with Dr. Kovac when he pays too much attention to her son.

To everyone's amazement, Lewis makes a date to share a home-cooked dinner with the elderly Ben Hollander (recurring guest star, Emmy Award winner BOB NEWHART - 'Newhart'), her depressed patient who is going blind. Lewis also treats a stressed housewife, makes plans to meet with the Internal Revenue Service for a tax audit and even finds time to hide Romano's prosthetic arm. Meanwhile, Neela and Pratt treat a vulnerable 18-year-old who was attacked in jail, and Gallant gambles with a risky hospital transfer to help a young septic cancer patient. Kovac clashes with Corday over the treatment of a patient who Corday suspects needs an appendectomy, and nurse Sam leaves her precocious son, Alex (recurring guest star OLIVER DAVIS), in the emergency room--where the boy gets an advanced education in medicine--for a day.
