Invitation to Love is a fictional soap opera in Twin Peaks. It is seen briefly on TV screens in all seven episodes of the first season and was shot in the Ennis House. The show sometimes acts as a commentary on events unfolding in Twin Peaks itself, highlighting some of the more outlandish or melodramatic elements of the show. The most obvious example of this "show-within-a-show" commentary can be found when Maddy Ferguson, the near-identical cousin of Laura Palmer, first arrives in Twin Peaks. Just before Maddy first appears on the show, an episode of Invitation to Love is shown in which it is revealed that there are identical twin characters in Invitation to Love who are played by the same actress, much as Maddy and Laura Palmer are almost identical, and are both played by Sheryl Lee. It is also implied in the brief snippet of the show that is shown that Jade and Emerald, the two characters in Invitation to Love, are characters with very different personalities, much as sweet and innocent Maddy is diametrically opposed to the dark and secretive Laura in Twin Peaks.
Another example can be found in the final episode of the first season, when Leo Johnson is shot in a dramatic fashion, and a similar event is shown happening to the character of Montana in Invitation to Love. Lynch later reused the motif of a show-within-a-show in his film Inland Empire (2006), which incorporated a secondary series, Rabbits.
