The daughter of Cord and Tina Lord (and younger sister to Clinton James "C.J." Roberts), Sarah is born in 1991.
Johnny's father Carlo wants to take his grandchild from Tina, who flees to Texas. Armed with medical proof that the baby is his, Cord follows. Tina goes into labor in a snowstorm, and with the help of Cord and DuAnn Demerest, gives birth in February 1991. She and Cord name their daughter Sarah Victoria, after presumed-dead family member Sarah Gordon Buchanan (abducted and apparently killed by Carlo Hesser) and Viki. Cord and Tina return to Llanview and remarry.
Rapist Todd Manning escapes from prison, but saves the lives of Sarah, C.J. and their cousin Jessica Buchanan. A man named David Vickers comes to town, claiming to be Tina's secret brother; soon Tina joins forces with imposter David to swindle the massive inheritance from her and Viki's real brother: Todd Manning. Ultimately, Tina moves to Baltimore with C.J. and Sarah in 1996, the three returning briefly in 1997 to say good bye to Cord as he leaves for London.
Sarah is terrorized and nearly murdered by the Music Box Killer in 2004; he strangles her, but she survives and her voice is saved. Cord arrives to bring her back to London for further recovery, and she breaks up with Riley in a "Dear John letter."
When Blair arrives in Chicago with Cristian Vega and Rex Balsom, Hunter had moved Todd to parts unknown but Blair recognizes the caller: Sarah. She tells Blair and the others what little she knew of the situation, but Sarah has no idea where Hunter had taken Todd. After Hunter threatens Sarah on the phone, Cristian and Rex insist she return with them to Llanview and stay with either her mother's sister Viki Lord Davidson or her paternal grandfather Clint Buchanan; not eager to reunite with her family, she refuses. Sarah finally agrees — if she can stay with Rex or Cristian. Sarah claims she has been staying "off the Buchanan grid" and living off money from her parents, who believe she is abroad with an important job.
In August, Hunter finally tracks down Sarah, first seeing her leave her great-grandfather Asa Buchanan's mansion. He follows her to Antonio Vega's club Capricorn; inside the empty club, he demands money. Cristian appears, and after Sarah cannot convince her father over the phone to send any money, there is a struggle between Hunter and Cristian over Hunter's knife. Hunter is stabbed, and dies shortly thereafter. Sarah goes to the Buchanan mansion to speak with Asa, but Clint tells her that Asa had died the night before. Sarah's father Cord comes to town for the funeral; she and Cord have a brief but loving conversation, and he returns to London.
Strapped for cash, Sarah takes a job as a waitress at Capricorn. Not any good as a server or bartender, Sarah pressures club manager Cristian for more responsibilities, in particular a position as talent booker, supposedly her area of expertise. Cristian refuses repeatedly, insisting that she needs to prove herself first. Sarah had been rooming with Cristian; overhearing that Layla Williamson is looking for a new roommate, Sarah nominates herself. Cristian gives Sarah a recommendation. Cristian finally challenges Sarah to book a major talent to perform at Capricorn, never expecting that she can do it. Owed a favor by hip-hop star Timbaland's manager, Sarah manages to book Timbaland to perform on October 9, 2007.
