Challenges at work and at home overlap in the series that remains the right prescription for powerful entertainment. Carter's playful office love affair becomes a 24/7 crisis. Kovac's partying affects his performance. And be careful what you wish for, staffers: Weaver is indeed promoted to a position outside the ER...but Romano replaces her. No wonder Kovac and Carter decide it's time for a change. They opt for assignment in Africa. What awaits them makes County General look like a stroll along the lakeshore.
