Dallas begins with a Romeo and Juliet theme. Bobby James Ewing, the youngest of the Ewing sons, marrying Pamela Barnes. Pamela (Pam) is the daughter of Digger Barnes who just happens to be the enemy of the the head of the Ewing Family, Jock Ewing. Digger also shared a romantic past with Jock's wife Ellie. The marriage does not sit well with any of the Ewings. Sue Ellen resents the newcomer, Lucy tries to intimidate her from the beginning, and Jock is furious. J.R reacts the most strongly, trying to break up the couple by using Ray Krebbs, the ranch foreman of Southfork, to break the couple up. Ray had a brief fling with Pamela Barnes, and J.R hopes this will end the marriage.

Lucy Ewing is skipping school, and spending most of her time in the hayloft with Ray Krebbs. Pam, still not fitting in with the Ewing Clan, decides Lucy is her ticket in. Pam decides she will 'mother' Lucy and get her back in school. Lucy doesn't like her Aunt's interference, and up's the anti by claiming the guidance counselor sexually assaulted her. Pam, in the first of the 'Pam saves the day' episodes, finds out the truth and gets Lucy to tell the truth and return to school.

Cliff Barnes, Pam's brother is not pleased that his sister has married a Ewing. A document Bobby asked Pam to bring to Ewing Oil ends up in Cliff's hands, so all the Ewings blame Pam. Is she a Spy in the House?

Luther Frick and his buddy find out that J.R Ewing and Ray Krebbs have been having a little fun with thier women, so they decide payback is in order. They go to Southfork while most of the Ewing men are away and hope to do the same with the Ewing women. They kidnap Pam, Sue Ellen and Lucy and seek revenge.

The Ewings hold the family's annual Barbecue, and as usual the sparks fly. Digger's appearance pleases Ellie but annoys Jock. Lucy is thrilled Pam's cousin Jimmy is in attendance, and she shows him the hay loft. Bobby and Pam announce that Pam is pregnant. The fact that Pam is pregnant upsets Sue Ellen and J.R. Sue Ellen drowns her sorrows in the bottle.
