Philadelphia — Who did Hillary Clinton’s team turn to to create the biographical story of her life? The creator of the TV show “Scandal,” of course.

The TV powerhouse Shonda Rhimes, who created the ABC drama about a Washington fixer caught up in a steamy web of sex and betrayal, has made the five-minute video that will be shown on the final night of the Democratic National Convention, according to a person with direct knowledge of the convention planning who would only discuss the video on the condition of anonymity.

Ms. Rhimes has supported Mrs. Clinton throughout her campaign, having produced a television commercial for her during the Democratic primary.

The video will be centered largely on Mrs. Clinton’s mother, Dorothy Rodham, who was born into poverty and neglect on the day that the United States Senate affirmed a woman’s right to vote and whose story will form the emotional core of the message Mrs. Clinton hopes to impart on viewers Thursday night.
