"McCord, most recently seen as Naomi Clark on '90210,' will play Heather, a 20-something ranch hand with a troubled ex-husband and a 5-year-old son," a synopsis said. "Having grown up in a house with four brothers, Heather is quite capable of handling herself around the Southfork ranch hands, but when her ex-husband returns, bringing turmoil back into her life, Christopher steps in, helping Heather resolve the conflict, and the two become involved in a romantic relationship."
Season 3 of the show is to begin this winter.
