COLD OPEN. Darkness, muffled hum, a horn blares. Light bleeds in — we are on the ground, looking up. Will's face leans into frame (POV from Hannah lying on the street after a car crash). He strains to move something pinning her, can't budge it. "Just hold on for me." He reaches toward us — THE HUM builds, snaps to silence.
Hannah bursts out of the house, nearly tripping over the threshold. She fumbles for her phone and calls Lily — goes to voicemail. She leaves a panicked, rambling message about Josh pretending not to know her. She speeds up. Someone grabs her shoulder from behind and spins her around — it's WILL, the man from the crash. "Hannah, hang up." She's terrified. He tells her he was at the crash. Her face freezes mid-sentence. THE HUM builds.
CAFÉ. A coffee cup clinks down. Hannah leans back, arms crossed. Will sits across from her. "You're a time traveller." He confirms it. He explains time travel using sugar on the table — pouring a straight line for the timeline, showing how consciousness jumps back. He produces a folder stuffed with handwritten notes, diagrams, photographs. He explains there are two versions of her: the 2018 Hannah whose body she's in, and her 2025 consciousness. He proposes a plan: go back to when she first met Josh at a park café and recreate the meeting.
Will and Hannah walk with purpose through a narrow alley, walls covered in old tags and peeling posters. Hannah asks how precise the trip will be. Will explains he can narrow it to the day but they'll end up wherever their bodies were at that moment. "The earth moves through the galaxy at 200 kilometres a second." Hannah rehearses the plan: verify the date, meet Josh at the park café.
Hannah moves fast through the city street, past storefronts and blurred faces. She rounds a turn — SMACK. She collides full-force with someone. A firm grip catches her shoulders: WILL. But this Will doesn't know her — he's startled. She calls him by name. An awkward exchange: he insists they've never met. She runs off. He calls after her: "Don't make me come find you!"
City park. Hannah storms away from the café terrace, hands clenched, breathing hard. Will calls her name (O.S.). She ignores him, quickens pace. He catches up, grabs her shoulder. She whirls around — "Don't touch me!" They argue: she says he lied about fixing things, he says they need to go further back. She's furious and desperate. "I WANT TO GO HOME!" THE HUM builds.
RESET. Close up on Hannah — distant, hollow. The same street as the opening, the same moment. She takes a step forward — a hand yanks her back. A car blurs past, air stirring her hair. She turns: it's Will. This time, she's saved.
Sunset on the front steps of a quiet street. Hannah has her knees drawn up; Will walks up and sits beside her. They discuss what went wrong — Josh was with someone else, the original timeline is lost forever. Will talks about destiny and control. Hannah reveals she ran into an earlier version of Will before meeting Josh. They agree to keep trying — Hannah says "We're just beginning."
INTERCUT with 1.17. Will alone at sunset. He opens his notebook — ON THE PAGES: dozens of handwritten notes, drawings, and diagrams. He turns a page. A photograph of Will and Hannah as a couple. He watches her walk away. A small, controlled smile.
Hannah exits the café, cuts into foot traffic, and thumbs a call. She tells Will (V.O.) that Julia is at the café. Will asks if it's a coincidence. Hannah realises this might be the first time Josh and Julia meet. Will tells her to wait and then change it.
Will and Hannah walk-and-talk in the office hallway. "Que sera, sera" — a light, reflective moment. Will asks where she'll go now. Hannah says she's currently occupying her 2018 body during a blackout.
Will exits Maya's building carrying the giant Hugzilla, which blocks his sightline. A cyclist — GRAHAM — slams into him. Will falls. Graham hits the pavement, blood at his hairline. Will tries to help; Graham coughs, bleeds.
Evening. Will and Graham walk a sodium-lit street, shutters half-down, shop lights dying. Graham grabs Will's arm and rewinds time — they're on the same street, earlier. Graham explains the rules of travel: can't go before birth or after death, always end up wherever your body was.
Two years later. Will sits under a tree on a park hill, reading his notebook. IRIS walks up and sits beside him. They greet casually. A quiet, reflective beat.
Friday night bar atmosphere. Will stands at a high-top with Iris and friends, slightly drunk. He threads through the crowd to the bar, where he meets HANNAH — she strikes up conversation. They talk about grief, Julia's sister, meeting people. Then JULIA steps up, introduces herself. She's with Hannah — puts her arm around her.
University cafeteria. Bright, high glass, pendant lamps. Will sits at a table. Hannah approaches, spots him, sits nearby. They talk about how they keep running into each other. Hannah mentions Julia's sister. Will mentions Maya died. Hannah extends sympathy — a genuine connection.
Same café, corner window table. JULIA in the black dress comes out of the bathroom and crosses to the counter where JANA serves her. Julia's phone dies trying to pay. WILL appears and swipes his phone to pay for her latte — taking Josh's original role. Julia is surprised and grateful. HANNAH is also present. Timeline has been altered.
Street. Will walks away from the café. GRAHAM intercepts him — says Will has changed something. Graham is furious, grabs Will's wrist. "This isn't a game."
Midday. Will suddenly appears on a street holding a coffee cup. No sign of where he is. He walks, then hears a car crash O.S. He rounds the corner and finds HANNAH lying on the street, dying. Blood, broken glass. Will panics — this is the consequence of his changes.
THE HUM fades. Hannah is in their bedroom, searching drawers and nightstand for Will's diary. She goes through piles of clothes, cupboards. Nothing. Then Will's silhouette fills the doorway. He found her.
Their bedroom. Will confronts Hannah — "Did you really think I wouldn't find out and travel back here?" Hannah: "It's too late. She's out there." Will reveals the diary isn't here. They argue about control, happiness, and what he's done to her life.
Their bedroom. Will and Hannah argue fiercely. "You turned my life to hell." "I saved you." "And then you changed everything." Will threatens: "If that's a problem, I can change it again. Oh. I just did."
Bar, evening. WILL and MAYA sit together in an alcove booth. HANNAH arrives and confronts Will. She's found him spending time with Maya. Tension and anger.
City park. HANNAH at the spot where she first met Josh. WILL arrives. Josh is somewhere nearby. Three characters but the focus is Will and Hannah — their alliance is fracturing.
Outside Maya's building. WILL orchestrates GRAHAM's bike crash — causes it intentionally this time. Graham hits the ground. MAYA is visible from an upstairs window, looking down. Will is manipulating events.
Will and Hannah's kitchen. WILL tells HANNAH about the "success timeline" — the ring, the exhibition in Berlin, the life they could have had. He's trying to convince her.
