Dr. Weaver finds herself in a deep hole when she bends the rules to treat the syphilitic lover of her powerful new patron -- Alderman Bright -- 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 and Dr. Carter and Abby reassess their relationship. Elsewhere: Dr. Kovac 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.
