Logline
When a railway clerk receives her dead sister on the midnight return train while her living sister is upstairs, she must stop its director from using future returns to coerce the living before he murders her sister to protect the service.
Characters
Mara Venn, 34, the night clerk, wants her sister alive and the return service intact: her mother's only visit is booked for Friday. Mara holds the token-vault key and can deny the director his next passengers. She has hidden irregular orders to keep her mother's appointment, giving Noor evidence that could cost her the vault.
Noor Venn, 29, a signal mechanic, wants to destroy the line after finding future dates in its dispatch system. She will sacrifice their mother's visit to do it. She knows how to stop the engine, but needs the signal key in Mara's vault. Her plan would erase whichever living person has to board the train.
Director Rusk, 61, wants exclusive control of the five-day forecasts, which have let him prevent accidents by coercing people before they make dangerous choices. He controls the date wheel and the return appointments. He can cancel Mara's reunion. Noor sabotaged his destination selector while investigating the engine; she can repair the fault sending his private passengers into public stations.
World rules
- Burning a registered personal token summons its owner from the date set on the engine. Metal left in the ashes is spent. If that person is alive on that date, nobody arrives. The official service selects past dates; the wheel can also reach five days ahead. A future return proves a possible death, and the living can still prevent it.
- Each person may return once. The limit follows the person across changed futures. An early return spends the goodbye they might otherwise have had after their eventual death.
- A passenger has eleven minutes on the platform. The final bell takes them back. They remember their life up to death and may lie or refuse to speak. Their possessions cannot leave the platform.
- A living person can enter the train. Crossing its threshold erases that person from living memory. Physical records survive, but a photograph cannot restore anyone's recognition of the person in it.
- The engine stamps a copy of each dispatch order into the receiving station's brass register. The signature is a copied imprint, not proof of consent. Clerks can add permanent annotations with a steel point.
- The only brake that can destroy the date wheel is inside the moving engine. Once pulled, it ends every pending return. There is no replacement wheel.
Five-episode outline
- The wrong date. Mara receives Noor's future corpse and a warning about a white signal lamp. Upstairs, living Noor has come to steal the register. Mara hides the arrival from Rusk and gives Noor the vault key; their mother's Friday appointment makes her refuse to destroy the wheel.
- The people who stayed home. The sisters trace Rusk's forecast requests to people pressured into abandoning trips or jobs. One token belongs to a boy who survived an accident but has already spent his return. Noor steals Rusk's private dispatch list. Mara keeps their mother's token out of the evidence bag.
- An appointment for Friday. Rusk offers to keep their mother's return if Mara identifies Noor's hiding place. Mara finds that he has already copied her signature from a coal receipt onto the order carried by Noor's corpse. He queried Noor's death to check that his planned attack would work. Mara refuses his offer and shows Noor the forgery. Noor cuts the station's outgoing signal, trapping Rusk's guards on the wrong siding.
- White means proceed. Rusk sets a white lamp to summon his guards, the light Noor's corpse described. Mara uses the public register to show the waiting families whose living relatives were queried without their knowledge. Rusk starts the engine with their mother's appointment still inside it. Noor can restore the track signal, but someone must board to reach the brake.
- The name in the book. Mara etches her account beside entry 604, then enters the engine and pulls the brake while Noor holds the signal at stop. The wheel breaks; Noor lives past her forecast death. Their mother's return is lost, and Noor no longer remembers having a sister. Rusk's copied orders and Mara's annotations survive in the brass register. Noor opens the station as an evidence room, where an unfamiliar woman asks to see entry 604. Beside the forged dispatch order, Mara has scratched: I gave my sister the key. She believed me.
