Greene (Anthony Edwards) treats a horse suffering from colic and very loose bowels. A wounded gunman is brought into the ER with explosives wired to his body, making it necessary to "defuse" the man before he can be treated. Carter (Noah Wyle) intubates an elderly and anonymous female patient, only to find that her HMO won't admit her to the ER without permission from her next of kin. Both Ross (George Clooney) and Anspaugh (John Aylward) have news that is guaranteed to make Weaver (Laura Innes) unhappy. And after working hours, Carter sets up a date with a former patient, an aggressive insurance salesperson named Roxanne (Julie Bowen). ~ Hal Erickson, Rovi
