Heiress Fallon Carrington is unhappy to find her billionaire father Blake engaged to Cristal Flores, and plots to drive a wedge between them by giving her father photos of Cristal with her former lover Matthew Blaisdel. Fallon's plan backfires, pushing up the wedding and securing Cristal the promotion Fallon wanted for herself. Feeling under appreciated by Blake, Fallon sets herself up as his business rival, backed by Blake's nemesis, Jeff Colby. Anders, the Carrington family butler, makes his knowledge of Cristal's shady past known to her, and the arrival of her opportunistic nephew Sam, who has just slept with Fallon's brother, Steven-puts her in further jeopardy. Matthew is killed in the aftermath of a suspicious explosion, and his unstable wife Claudia appears at Blake's wedding to accuse him of her husband's murder.
