Penniless student Lucy in 2026 finds Locker 17, a time‑link to 1964, where 37 survivors are trapped at Holloway High under the cruel superintendent Crow. Resourceful Adrian leads them to fight back. Lucy sneaks supplies through the locker despite her aunt Marian’s threats, and a cross‑time bond forms. But the locker has a fatal catch: living things cannot pass through safely. When greedy Marian steals the key bronze badge to exploit the locker, both timelines are put at risk. Adrian crosses to 2026 at the cost of his life. Lucy races to fix the badge and stabilise the locker. They open a real time passage, rescuing all survivors. The long‑buried tragedy ends, and Lucy and Adrian gain a future beyond the locker.
