演员Ben Glenroy（保罗·路德 Paul Rudd 饰）在第二季结局中令人震惊地去世后，Charles（史蒂夫·马丁 Steve Martin 饰）、Oliver（马丁·肖特 Martin Short 饰）和Mabel（赛琳娜·戈麦斯 Selena Gomez 饰）开始调查这起发生在Oliver负责的百老汇节目幕后的悲剧。 在节目联合主演Loretta Durkin（梅丽尔·斯特里普 Meryl Streep 饰）的帮助下，三人组发现这起案件比Arconia的谋杀案更难侦破，但仍然乐观地认为，他们会找到谁杀死了Oliver的男主角，而Oliver也试图将自己的节目重新运作起来。
由于剧院里的每个人都可能成为嫌疑人，三人组的破案工作十分艰巨。至少他们的粉丝们会得到全新的一季播客。
The series is set inside the bubble of Silicon Valley, amid misguided corporate cultures, moony innovation labs and cutthroat private high schools. It is centered around a rift between a self-appointed “inventor of the future” tech CEO and his self-serving “performance psychologist”, who are engulfed in a scandal sparked by the exploitation of personal data.
But 9-1-1 could get another spinoff on ABC in a new location, with Las Vegas among potential cities rumored to follow Los Angeles (9-1-1) and Austin (9-1-1: Lone Star).
