"Where the Heart Is"
The ER staff finds themselves being pushed to the limit and beyond when Derek Fossen, the father of Ben Fossen who Greene treated last week goes on a rampage through Chicago, unleashing a trail of destruction while Chen moves one step closer to achieving her dream of becoming Chief Resident and Weaver confronts Romano over Romano firing Legaspi.
Cleo and Benton are both left extremely concerned when Cleo cuts her hand while treating a patient who's HIV-positive and Carter considers his future.
DR. GREENE'S NEW FAMILY COULD BE IN DANGER AS SHOOTER GOES ON RAMPAGE THROUGH CHICAGO IN SEASON FINALE: The ER is overwhelmed with gunshot victims when a distraught father (guest star Ted Marcoux) goes on a murderous spree at a foster care facility and a horrified Dr. Greene (Anthony Edwards) realizes that his personal connection with the madman may prove fatal for his new wife (Alex Kingston) and their baby.
In the midst of the chaos: Dr. Carter (Noah Wyle) is put in the awkward position of helping Dr. Chen (Ming-Na) apply for the promotion that he himself was denied, Dr. Benton (Eriq La Salle) is unexpectedly assaulted by his ex-girlfriend Carla's husband (guest star Victor Williams) and Dr. Finch (Michael Michele) cuts her hand while treating an HIV-positive patient.
Meanwhile, Dr. Romano (Paul McCrane) betrays his prejudice when he tries to force out Dr. Legaspi (guest star Elizabeth Mitchell). Laura Innes, Goran Visnjic, Maura Tierney and Erik Palladino also star.
The ER is flooded with foster care home residents, attacked by a shooter bent on tracking down his son, who, with the help of Dr. Green, was put into the foster care system amid allegations he was being abused by his father.

Robert Romano: You had better choose your battles very carefully, Kerry. You are the Chief of Emergency Medicine. Not the County's lesbian advocate.
Kerry Weaver: That's where you are wrong, Robert. I am the Chief of Emergency Medicine and I am a lesbian. And if you pursue this matter any further I'll take it to the County Board of Supervisors, the ACLU, the press and anyone else who cares to listen. So I suggest that you choose your battles very carefully.
