The series, created by Richard and Esther Shapiro and produced by Aaron Spelling, revolves around the Carringtons, a wealthy family residing in Denver, Colorado.

In season three, Dynasty introduced Gordon Thomson in the role of Adam Carrington, Blake and Alexis' eldest child, who had been kidnapped as an infant and never found.

In the meantime, Adam, the long-lost son of Alexis and Blake who had been kidnapped in infancy, reappears in Denver and almost starts an affair with Fallon before they discover they are siblings.

Also introduced are Krystle's ex-husband, tennis pro Mark Jennings, and Kirby Anders, the daughter of longtime Carrington majordomo Joseph.

In the middle of the season, news that Steven has been killed in an accident in Indonesia comes to the Carringtons; he survives, but undergoes plastic surgery and returns to Denver.
