Playing to disappointing ratings during its first season on the air, the Dallas spinoff Knots Landing made a spectacular leap forward during Season Two with the introduction to the cast of Donna Mills as Abby Cunningham, the manipulative and predatory sister of Sid Fairgate (Don Murray), Gary Ewing's (Ted Shackelford) boss at Knots Landing Motors. Abby also brings along her children Olivia (Tonya Crowe) and Brian (Bobby Jacoby), who in their own way will be just as important to the overall scheme of things as their redoubtable mom. In addition to bringing Abby into the fold, Season Two wastes no time plunging the characters into a morass of intrigue as Sid Fairgate is accused of raping a nubile hitchhiker. Around the same time, several more recurring characters are introduced, among them Scooter Warren (Allan Miller), the new boss of real estate agent Laura Avery (Constance McCashlin); sexy female auto mechanic Linda Striker (Denise Galik); and Roy Lance (Steven Hirsch) the shady owner of the Orchid Cab company. Among the major plot developments this season: Abby has an affair with Laura's lawyer husband Richard (John Pleshette) the Wards break up when Ginger (Kim Lankford) finds out that her record-exec husband Kenny (James Houghton) has slept with Kristen Shepard (Mary Lee Crosby), aka "The Girl Who Shot J.R." on Knots Landing's parent series Dallas (and as for J.R. [Larry Hagman], himself he shows up long enough to have his own tryst with Abby); and weak-willed former alcoholic Gary Ewing once again betrays his long-suffering spouse Val (Joan Van Ark) by fooling around with Judy Trent (Jane Elliot), the wife of Earl Trent (Paul Rudd)--whom Gary has sponsored for membership in AA! The final two episodes of the season were originally telecast back to back on the same night: In "Designs," J.R. Ewing makes yet another appearance to bedevil brother Gary; and in the (literal) cliffhanger "Squeezeplay," Sid agrees to help the FBI in their sting operation against the crooked Orchid Cab Company--and as a consequence, he is involved in an "accident" as his car goes out of control and plummets over a cliff.
