CAN DR. WEAVER FIND HER WAY OUT OF A DEEP ETHICAL WORMHOLE?

Dr. Weaver (Laura Innes) finds herself in a deep hole when she bends the rules to treat the syphilitic lover of her powerful new patron -- Alderman Bright (guest star Bruce Weitz, "Hill Street Blues") but when the patient has a severe allergic reaction, she desperately tries to cover her tracks and compromises her ethics even further. In the meantime, Weaver's career continues to get a boost at the expense of a stubborn Dr. Romano (Paul McCrane) and Dr. Carter (Noah Wyle) and Abby (Maura Tierney) reassess their relationship. Elsewhere: Dr. Kovac (Goran Visnjic) ruminates aloud on his star-crossed career path while he ministers to a rebellious teenaged girl who claims she was sexually abused at a boot camp for wayward youths, and Carter cares for a nasty middle-aged woman who's slowly being poisoned. Alex Kingston, Ming-Na, Sherry Stringfield and Sharif Atkins also star..
