Plot synopsis

Continuing the events of last season, the smallpox crisis continues to escalate and Carter, Abby, Chen, Pratt and a patient named Stan are all quarantined. When the CDC confirms that the outbreak is a mutated form of monkey-pox originating from the Congo, Lewis is ordered to evacuate the entire hospital.

Gallant begins inoculating everyone locked down in the ER while Weaver aids the evacuation from outside in the ambulance bay. On the roof Romano, Kovac and Lewis argue over the use of the last remaining helicopter. In the chaos, Romano backs into the choppers tail rotor and his arm is severed off above the elbow.

Kovac and Lewis attempt to stabilise him and Kovac is forced to take him back down to the deserted ER where he’s aided by Chen and Pratt who fight to keep him alive, leaving Lewis trapped on the roof with a dying patient. Anspaugh arrives with a surgical team and are allowed into the ER to attempt to reattach Romano’s arm while Gallant fails to reach Lewis in time before her patient dies.

Two weeks later, the ER is re-opened and Carter and the others are given the all clear. Meanwhile, Corday has returned to England and is now working at her father’s private hospital. However, her Americanised ways do not go down well with her new colleagues and realising that County is where she truly belongs she decides to return home to Chicago.
