Full Story Summary: Every Twisted Turn
Spoilers ahead. This section reveals every major plot event, including the ending.
Millie Calloway loses her job with the Degraw family and faces eviction from her South Bronx apartment.
She interviews with Douglas Garrick, a polished tech CEO who offers generous pay to clean his penthouse and prepare meals for his wife, Wendy. Douglas gives one rule: never disturb Wendy, who is chronically ill and stays in a locked guest room.
Millie notices strange details immediately. Wendy’s sobbing filters through the door at odd hours. A nightgown in the laundry bears bloodstains.
A bloody handprint appears on the bathroom wall. Millie breaks the rule and enters Wendy’s room, finding a woman with a face covered in brutal bruises.
Wendy tells Millie that Douglas is starving and beating her.
He controls everything — cameras, finances, even the locks. Millie, who served prison time for killing a man who attacked her friend, feels an overwhelming duty to act. She arranges a rental car and drives Wendy to a safe farm in Albany.
During the trip, Millie spots a black Mazda with a cracked headlight tailing her. She later confronts the driver and discovers it is Enzo Accardi, her former boyfriend and partner from Italy. Enzo explains he never stopped watching over her.
Wendy calls Millie days later in a panic: Douglas found her and dragged her back to the penthouse. Millie rushes over and hears choking sounds through the door. She grabs a gun hidden inside a hollowed-out dictionary — placed there earlier by Wendy — and shoots the man attacking Wendy.
He collapses. Wendy urges Millie to flee and delete all their messages, promising to claim self-defense.
At the police station, Detective Ramirez questions Millie.
She is not arrested. A hidden camera on the penthouse’s back door proves Millie was never present at the same time as the real Douglas Garrick. Millie sees Douglas Garrick’s photograph on a news broadcast and freezes. The man she shot is a stranger. The man who hired her was an impostor.
The narrative shifts to Wendy’s perspective. Wendy married Douglas for his money but grew to despise him. She began an affair with Russell Simonds, a furniture restorer married to Douglas’s loyal assistant, Marybeth.
Douglas discovered the affair and prepared to divorce Wendy, triggering a prenuptial clause that would leave her destitute.
Wendy and Russell devised a plan: hire a housemaid with a violent criminal record, stage elaborate abuse, lure her into “rescuing” Wendy, and frame her for Douglas’s murder.
Russell played the role of “Douglas Garrick” throughout. The real Douglas was never at the penthouse when Millie was there. After Millie shot Russell with a gun loaded with blanks, Wendy murdered the actual Douglas herself.
Millie and Enzo track Wendy and Russell to a remote cabin. Millie realizes she lacks the evidence to involve the police. Instead, she visits Marybeth Simonds and reveals everything — the affair, the murder, the framing.
Marybeth drives to the cabin with a knife and a vial of digoxin, a heart medication Millie stole from her ex-boyfriend Brock.
Marybeth slits Russell’s throat while he sleeps. She forces Wendy to write a confession and suicide note, then administers a lethal dose of digoxin.
The deaths are ruled a murder-suicide.
Millie is cleared of all suspicion and moves in with Enzo.
