Contents 1 Plot 2 Production 2.1 Filming 3 Release 3.1 Critical reception 4 References 5 External links Plot In suburban Connecticut, upper - class high schooler Amanda ( Olivia Cooke ) euthanizes her crippled horse with a knife, resulting in charges of animal cruelty. Some time later, Amanda arrives at the home of the more popular and academically - inclined Lily ( Anya Taylor - Joy ). The girls had previously been best friends but grew apart after the death of Lily 's father. They meet under the pretense of hanging out and having a casual tutoring session, but Amanda knows that her mother ( Kaili Vernoff ) has paid Lily to socialize with Amanda. Lily denies being paid, but Amanda, left emotionless by an unspecified mental disorder, is unfazed. Lily meets with Amanda again, this time voluntarily, and they rekindle their friendship. Lily lives with her mother Cynthia ( Francie Swift ) and stepfather Mark ( Paul Sparks ), a wealthy but abrasive man whom she hates. One night, Amanda asks if Lily ever thought about killing Mark, upsetting Lily. However, tensions flare between Lily and Mark when Mark enrolls Lily in a boarding school for girls with behavioral issues. After seeing him berate Cynthia, Lily reconsiders and calls Amanda about the notion of killing him. She proposes that Amanda perform the murder as she would be free of guilt while doing it. However, Amanda believes that her pending animal cruelty trial would make her an immediate suspect, and they decide instead to blackmail drug dealer Tim ( Anton Yelchin ) into murdering Mark while both of them are out of town. The night of the planned murder, Tim arrives on the property but leaves without killing Mark. The girls agree not to contact Tim again, as his own criminal history will prevent him from alerting the police. Lily impulsively prepares to kill Mark herself but is talked out of it by Amanda. One night, Lily and Amanda are watching a film at home when Lily reveals that she has spiked Amanda 's drink with Rohypnol, planning to stab Mark to death and frame Amanda. Lily attempts to back out of the planned murder, but Amanda willingly finishes the drink. While Amanda is unconscious, Lily murders Mark and rubs Amanda with his blood, crying and holding the unconscious Amanda for comfort. Some time later, a recovered and confident Lily encounters Tim, who now works as a restaurant valet. Following Mark 's death, Lily has once again found academic success and is interviewing for college admission. Lily gives Tim the tape which she was going to use to blackmail him. She then mentions a letter from Amanda, who has been institutionalized in a psychiatric hospital for Mark 's murder. The letter is shown to detail Amanda 's experiences at the institution and a recurring dream about a future in which the humans let the community fall into disarray due to their vanity and it becomes overrun by thoroughbred horses. When Tim asks what the letter said, Lily says she threw the letter away without reading it. Production The script, which Finley had expected to be produced as a stageplay, was instead acquired for production as a film by companies B Story ( Nat Faxon, Jim Rash, and Kevin J. Walsh ) and June Pictures. In April 2016, Olivia Cooke, Anya Taylor - Joy and Anton Yelchin were announced to have joined the cast. Finley would direct the film. Filming Principal photography began on May 9, 2016, in the Massachusetts towns of Cohasset, Tewksbury, Scituate, Westwood, and Wellesley, concluding on June 5, 2016, 14 days before Yelchin died. Finley said of his experience with Yelchin : `` The whole experience was really amazing. As soon as he came on board, we had a great dinner, where we talked about film noir as a genre. He was very keyed into that aspect of this movie, he loved film noir. I felt really, like I knew nothing about movies, talking to him. He was also the sweetest guy, he would never make you feel less - than for not knowing these things. He was just delightful and funny from the beginning, he was awesome throughout and brought a jolt of energy.
