WHEN MAC SUSTAINS A CONCUSSION IN A CAR ACCIDENT ON CHRISTMAS EVE, SHE FLASHES BACK TO A DOCTOR'S VISIT WHEN SHE WAS FORCED TO COME TO TERMS WITH WEBB'S DECEPTION, ON "JAG," FRIDAY, DEC. 17

"The Four Percent Solution" -- After suffering an injury in a Christmas Eve car accident, Mac recalls a doctor's appointment where she was forced to deal with Webb's dishonesty, on JAG, Friday, Dec. 17 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Bradford May directed the episode from a script by Don McGill, one of the series' co-executive producers.

While unconscious with a head injury, a Christmas Eve radio show sparks a memory for Mac when, plagued by insomnia after Webb's disappearance, she reluctantly sought the help of the psychologist who treated her after the hostage situation last year. But when the doctor refuses to give her anything without talking first, Mac is forced to face Webb's deceit.
