Shell

The opening scene showing Sam's murder is actually a flash-forward to the future. The movie then follows her story from months earlier when she undergoes the Shell procedure. This framing device shows the audience the danger Sam is in before revealing how she got there.

The mysterious crash Sam hears before being killed hints at the corporate conspiracy that will later unfold.

Chloe's condition worsened due to the Shell procedure's side effects. Dr. Hubert, who had a relationship with her, hid her in a locked room in his house where she had transformed into a feral creature. She later escaped and was transformed into a gigantic lobster-like creature before dying in the lab confrontation.

The tiny mole on Sam's neck that Hubert removes early on foreshadows the same transformation that consumed Chloe.

Detectives Flores and Abramson were covertly employed by Zoe Shannon to monitor Sam and prevent her from uncovering Shell's secrets. They posed as investigators looking into Chloe's disappearance while actually feeding information back to Zoe and blocking Sam's attempts to get help.

The detectives' claim that Sam's recording was illegal despite being evidence of a crime reveals their true allegiance.

The genetic rejuvenation procedure causes aggressive mole growth across the body, followed by severe physical transformation where clients devolve into feral, animal-like creatures. Chloe experienced this progression firsthand, transforming from a human into a feral being and eventually into a monstrous lobster-like form.

Dr. Brand explains to Sam that the side effects were known risks of the experimental genetic technology developed at Shell.

Hubert and Chloe were in a romantic relationship. When Chloe's side effects from the Shell procedure began worsening, Hubert hid her in his house to protect her from Zoe and Shell's leadership. He had been fired from Shell after trying to expose the dangerous side effects.

The medication Sam finds in Hubert's bathroom belonged to Chloe, revealing their connection before Sam discovers the locked room.

Zoe needed Sam to remain silent to protect Shell's reputation and avoid legal liability. The company was already facing scrutiny due to client disappearances. Zoe offered Sam a deal to buy her silence, threatening her when she refused. Later, Zoe admits she secured Sam's recent acting role out of pity, making her manipulation even more insidious.

Zoe's demand to see Sam's call log and her threat about news leaks reveal how far she'll go to control the narrative.

During the final confrontation in Shell's secret laboratory, Zoe trapped herself in a laboratory tube to escape Chloe's rampage. However, Chloe smashed the computer controls, triggering the experimental procedure to spiral out of control. The malfunction killed Chloe, and Zoe remained locked in the tube as the situation escalated beyond anyone's control.

Chloe's choice to spare Sam before turning on Zoe suggests she distinguished between victim and perpetrator.

Sam published the tell-all book to expose the truth about Shell's illegal experiments and warn the public, even though the company continued to thrive despite its crimes. The bittersweet ending shows Sam achieving personal and professional redemption through her truth-telling, while acknowledging that corporate power often remains unchecked.

The movie's dark tone and critique of beauty industry predation support Sam's decision to speak out despite the odds.

Cornelius was Zoe's driver and enforcer who carried out her dirty work. He ambushed and killed Dr. Hubert when Sam discovered Chloe's location, then abducted Sam to bring her to Shell's headquarters. He was ultimately killed by Chloe during the escape attempt.

Cornelius's interception of Sam and Lydia in the hallway shows he's been tracking them throughout.

Sam threw the tea in Zoe's face as a desperate escape attempt after realizing Zoe was manipulating and surveilling her. Zoe had brought tea to spy on Sam and demanded to see her call log, threatening her if news about the side effects leaked. Sam used the distraction to flee with Lydia's help.

This violent outburst marks Sam's turning point from willing participant to fugitive.
