Ally McBeal - Season 1 Episode 16
Forbidden Fruits

A high-profile case opens up for Cage and Fish when a jilted spouse plans to sue a U.S. Senator for "interfering with happy marital relations". The Senators case perversely parallels the awkward love triangle between Georgia, Billy, and Ally. Uncomfortable with how close the case mirrors her own life, Georgia quits the case; Fish and Cage step in to try and keep the Senator from losing his job.
