Synopsis by Hal Erickson
Future WKRP in Cincinnati star Loni Anderson appears as Susan Wallace, a fickle airline stewardess whom Jack (John Ritter) has fallen in love with. Things start to get complicated when Susan arrives unannounced at a surprise party that Janet (Joyce DeWitt) and Chrissy (Suzanne Somers) are throwing for Jack. As it turns out, the girls' "intrusion" in Jack's love life rescues him from the clutches of a woman who is planning to play him for a chump. This was the final episode of Three's Company's second season.
