As season nine of ER opens, a grieving Dr. Elizabeth Corday (Alex Kingston) elects to return to the ER after the death of her husband, Mark Greene. Meanwhile, Dr. John Carter (Noah Wyle) and Abby Lockhart (Maura Tierney) have survived the smallpox scare that caused the lockdown and riot at Chicago County at the end of season eight -- and as a bonus, they have fallen in love. Elsewhere, lesbian Dr. Kerry Weaver (Laura Innes) comes to grips with her pregnancy and subsequent miscarriage, and puts her job on the line by giving secret medical treatment to an alderman who still hasn't "come out." Dr. Romano (Paul McCrane) becomes even more irascible after losing his right hand and forearm in a helicopter mishap; no longer able to operate, he is placed in charge of the ER, where his erratic behavior soon proves to be not only annoying but dangerous. Troubled East European émigré Dr. Luka Kovac (Goran Visnjic) is accused of hitting on a nurse, becomes involved in a fatal traffic accident, and puts his job in jeopardy with a disastrous misdiagnosis. The tensions escalating between African-American ER staffers Gallant (Sharif Atkins) and Pratt (Mekhi Phifer) explode when both are temporarily held as suspects in a murder at the doctors' favorite watering hole, Magoo's -- and later, Pratt is on the verge of exiting the ER, but he redeems himself by saving the life of a mother whose baby was cut from her womb. Mercurial Dr. Chen (Ming-Na) reveals that she once gave up a child for adoption. Plagued by the psychological problems of her mother and brother, recovering alcoholic Abby begins drinking again. Lewis (Sherry Stringfield) returns from a brief holiday with a new husband (Donal Logue) in tow. And several episodes are built around Paul Nathan, an overaged medical student (Don Cheadle) suffering from Parkinson's disease. The year's most noteworthy newcomer is Leslie Bibb as brash, outspoken med student Erin Harkins. Season nine ends with the culmination of a story arc begun when Carter finds himself re-examining his priorities after a brush with a dedicated storefront-clinic doctor (Ed Asner). Ultimately, Carter joins Kovac in a Doctor Without Borders project, tending to the sick and wounded in a dismal Congolese field hospital while a political revolution rages around them.
