What more could we expect from Nine Perfect Strangers? Of course, the series ends with more acid trips, drugs, and more unexpectedly, a revealing backstory that differs from the plot of the book. Basically, at the end of Episode 7 of Nine Perfect Strangers, we see Carmel's (Regina Hall) foggy eye which proves that she was the person who shot Masha (Nicole Kidman) all those years ago.

Carmel is basically the reason that Tranquillum House exists. After she discovered Masha was having an affair with her husband, Carmel shot her, which led Masha to create Tranquillum House. Now, we realize that Carmel comes to Tranquillum House to see what Masha’s up to, and instead of kicking her out, Masha forgives Carmel and puts her in a sensory deprivation chamber.

After this, she goes to heal the Marconi family with a lethal amount of drugs … but luckily, the Marconis (knowing the risks) survive and are even able to speak to their late Zach (Hal Cumpston) to get some closure. Good for them, we guess?

But that still leaves Frances (Melissa McCarthy), Tony (Bobby Cannavale), Jessica (Samara Weaving), and Ben (Melvin Gregg). They each try to leave the retreat, but mysteriously can’t find their cars.

Instead, the escapees find Carmel in the sensory deprivation room — and Masha and Yao lock them inside. Those locked in the room smell smoke and hear the crackling of fire … leading them to believe they're stuck in a fire.

But it's just a therapy tactic Masha uses. Everyone is able to get out safely. Masha’s experimental therapies are far from legal. Delilah (Tiffany Boone) calls law enforcement, and Masha is arrested.
