"Disarming" -- Hanson and Seger treat a young soldier returned from Iraq who suffers a stroke for which they can't find the cause, on "3 Lbs.," at a special time, Tuesday, Dec. 5 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Nicole Kassell directed the episode from a script by executive producer Peter Ocko.

Cynthia Nixon guest stars as Hanson's ex-wife, Corine Dubinski, who is also the hospital's psychiatrist. Griffin Dunne plays Dr. Jeffrey Coles in a recurring role.

Clay Harper and his fianc�e, Cindy Harris, are in New York celebrating his return from Iraq when Clay suffers a debilitating stroke. Hanson and Seger are at odds on how to treat it: Hanson, always the cut and dried clinician, looks for hard medical facts. Seger thinks his recovery will also depend on the support he gets from Cindy. Both doctors need help when a clear diagnosis eludes them and Clay's condition worsens. They also treat Tilly Bates, an older woman whose brain tumor has made her a much nicer person.
