"Soap" is an American sitcom that originally ran for 85 episodes on ABC from September 13, 1977 until April 20, 1981. The show was created as a night-time parody of daytime soap operas, presented as a weekly half-hour prime time comedy. Similar to a soap opera, the show's story was presented in a serial format and included melodramatic plot elements such as alien abduction, demonic possession, murder, and kidnapping.

In the opening sequence of each episode the announcer says "This is the story of two sisters—Jessica Tate and Mary Campbell".

The Tates live in a wealthy neighbourhood. Jessica Tate (Katherine Helmond) and her husband, Chester (Robert Mandan), are hardly models of fidelity, as their various love affairs result in several family mishaps, including the murder of her sister Mary's (Cathryn Damon) stepson, Peter Campbell (Robert Urich).

Mary's family, the Campbells, are working-class, and as the series begins, her son Danny Dallas (Ted Wass), from her first marriage is a gangster-in-training. Danny is told to kill his stepfather, Burt Campbell (Richard Mulligan), who, Danny is told, killed his father. Mary's other son, Jodie (Billy Crystal), is gay, and contemplating a sex-change operation.

Each episode would end with the announcer asking a series of life-or-death questions in a deliberately deadpan style and concludes each episode with the trademark line, "These questions—and many others—will be answered in the next episode of..."Soap"."
