Lost in Time

In a near-future world, Absolom Sciences has built a machine that exiles convicted criminals into the distant past, serving as the ultimate crime deterrent. The technology, housed in a purpose-built city in the Nevada desert, has nearly eradicated violent crime worldwide. On the anniversary of his wife Sarah's death, physicist Sam Anderson visits her grave with his nineteen-year-old daughter, Adeline, and eleven-year-old son, Ryan. Drones and police surround the family; Sam is tranquilized and arrested. He wakes in custody, where Detectives Billings and Holloway charge him with the murder of Dr. Nora Thomas, his secret romantic partner and fellow Absolom scientist.

Sam is stunned. Surveillance footage shows he and Adeline were Nora's only visitors the previous evening. Sam explains the visit's true purpose: a blackmailer had photographed him kissing Nora at a conference in Davos, and they needed to tell Adeline about the relationship before the photos went public. Adeline reacted with fury, punching a wall and shattering picture frames. Both women bled from glass cuts, and Adeline stormed out. Sam insists Nora was alive when they left. His longtime friend and Absolom co-founder, Elliott Lucas, and the company's chief counsel, Tom Morris, arrive and halt the interrogation.

The detectives believe Adeline killed Nora in a rage and Sam helped cover it up. The murder weapon, a knife hidden in a toilet tank, bears Adeline's fingerprints and Nora's blood. Sam convenes the remaining Absolom founders: Elliott; physicist Hiroshi "Hiro" Sato; venture capitalist Daniele "Dani" Danneros; and ailing scientist Constance "Connie" Niven. Each provides an alibi. The group debates motives, noting that Nora had fiercely opposed Absolom Two, a secret next-generation prototype that Elliott and Hiro developed. After the meeting, Sam discovers a note hidden under the dining table demanding he confess to the murder by 5 p.m. or irrefutable evidence of Adeline's guilt will be sent to police. He suffers a panic attack and hides the note.

Celebrity attorney Victor Levy arrives and proposes a defense strategy, but Sam rejects it. He confesses to Nora's murder, claiming Adeline's prints are on the knife only because she tried to stop him. The deal secures Adeline's release. Sam privately asks Daniele to become his children's guardian and shares the threatening note with her. Daniele promises to find a way to bring him back. Before departure, Sam reveals to Adeline that the Absolom Six, the company's six founders, never believed their machine would work; they originally built it as a shipping technology to secure venture capital for personal financial emergencies. Daniele, then a venture capitalist, later saw its potential as a criminal justice tool. On departure day, Sam is drugged through his breakfast, wakes inside the Absolom chamber, sees his family through the glass, and is transmitted to the past.

Sam arrives in the Late Triassic period, roughly 202 million years ago, falling into a stormy sea in total darkness. He floats for two days before washing ashore on Pangea, the ancient supercontinent. Over the following days, he starts fires, crafts weapons from dinosaur bones and teeth, and fends off small carnivorous dinosaurs. He kills a crazed Absolom prisoner in self-defense and discovers small metal pins on the man's femur stamped with Absolom serial numbers. After a volcanic eruption forces him into open desert, he finds more pins on another human skeleton and realizes they function as directional locators with color-changing LEDs. Following their signal through devastated forest, Sam digs up a round metal device, connects the pins into a wristband, and turns the dial to on just as a dinosaur charges. The device, a recall ring designed to pull a traveler back from the past, activates, and the Triassic vanishes.

Meanwhile, Adeline investigates Nora's murder under a plan Daniele devises. She plants surveillance devices in Constance's home, discovering a spare room covered in photos, names, and death dates. She also installs a tracking device on Hiro's phone. Before the investigation progresses further, Daniele drugs Adeline with an injector, places her unconscious body in the Absolom Two prototype, and transmits her to March 17, 2008, at Stanford University.

Adeline lands on campus and orients herself through contextual clues: an Obama campaign T-shirt, discussions of the Bear Stearns collapse. She sits in on a psychology lecture taught by her mother, Sarah, who is visibly pregnant with the baby who will become Adeline herself. Adeline volunteers as an unofficial teaching assistant, giving only her first name. When she tries to sell the diamond earrings Daniele gave her, she discovers that her Absolom intern badge conceals a California driver's license beneath disappearing ink, bearing her photo but the name "Daniele Danneros," an anagram of "Adeline Anderson." The revelation is shattering: She is Daniele. She always has been. Daniele sent her younger self to the past knowing Adeline would become the woman who funds Absolom, raises her own younger self and Ryan, and orchestrates the entire story.

Adeline sells the earrings, obtains forged documents, and exploits her knowledge of the 2008 financial crisis to build a fortune through short selling and strategic investments. She spends the summer as her pregnant mother's helper, painting the nursery, assembling the crib, and becoming inseparable from the woman she lost as a child. On September 8, 2008, she drives her mother to the hospital and witnesses her own birth, then leaves the Bay Area to begin building the life she knows must come. Over the following years, living as Daniele Danneros, she founds a venture capital fund and invests in Syntran, a Korean biotech company led by CEO Hana Kim that grows synthetic organs and replica human bodies. She undergoes cosmetic surgery to avoid recognition, sends the email to Elliott that launches Absolom Sciences, and guides the company from start-up to global institution. She secretly builds a self-sustaining island refuge in the Pacific called Absolom Island and commissions Tesseract, a facial recognition system that searches historical archives for evidence of time travelers. She endures the deaths of Elliott's son Charlie and her own mother, unable to change either without rupturing the causal chain.

On the night of Nora's "murder," the older Adeline monitors events on surveillance feeds but cannot intervene. After Nora's body is found, she has the corpse exhumed and discovers a Syntran serial number proving it is a synthetic replica. Nora was never killed; she was replaced. Adeline recruits Hiro, reveals her true identity using Tesseract photos, and executes the final sequence: She sends her younger self to 2008, transmits a Syntran replica to the murder scene, and activates Sam's recall ring. Sam appears in the Absolom chamber, emaciated but alive, and Adeline sends him to Absolom Island.

Adeline and Sam then travel back to Nora's home on the night of the murder and stage the crime scene using the replica body. Elliott arrives unexpectedly with a gun, believing Adeline intends to kill Nora, but stands down when shown the truth. Adeline reveals her identity to her father and tells Elliott that his future self was present the night Charlie died, promising Elliott will get the chance to save his son. They ensure the forensic evidence matches the historical record and depart via recall rings.

On Absolom Island, Sam and Nora begin a new life together. Adeline reveals the truth to Ryan, proving her identity through private childhood memories, and relocates the family to the island. Constance, gravely ill, dies shortly after arriving. The island becomes a base for rescuing people from historical disasters, replacing them with Syntran replicas. Charlie is saved when Elliott talks him down from a fatal overdose and Adeline provides a recall ring. Hana Kim's father is extracted from Korean Air Lines Flight 007 before it is shot down in 1983. Sam articulates the underlying principle: By believing in and planning for rescues, they create the causal conditions for those rescues to have already occurred. Tesseract identifies dozens of future missions, and Adeline reconnects with Nathan Hill, a former romantic partner, inviting him to join the island's work, their shared future confirmed by photos already embedded in the historical record.
