DR. CARTER RISKS LIFE IN AFRICA WHEN HE VOLUNTEERS TO SERVE VICTIMS OF CONGOLESE CIVIL WAR -- In a change-of-pace episode, a sweat-soaked Dr. Carter (Noah Wyle) finally arrives in the war-torn Congo as part of a voluntary medical program and he finds primitive Third-World facilities, a few heroic staffers and woeful patients overflowing the tiny hospital while a bloody civil war threatens to engulf them all. Carter ventures deeper into the jungle to reunite with Dr. Kovac (Goran Visnjic) as they risk their lives manning a crude outpost used for a vaccination campaign -- and soon find themselves in the withering line of fire between the warring tribes.
