Twenty children from different parts of the world wake up in a sterile, high-tech research facility with no memory of their pasts. Each child is aged between 10 and 14. The facility is deep underground-or possibly even in a floating island or alternate dimension, for added mystery.
The researchers are strangely kind. They act more like loving guardians than cold scientists. The children receive education, food, medical care, and affection. But something feels... wrong. Each child is subjected to different "harmless" experiments: puzzles, emotional simulations, stress tests, or neurological scans.
Despite their comfort, none of them are allowed to leave. There are no clocks. No windows. No outside world. And worst of all:
No one remembers who they were before.
Suddenly, a group of hijackers crash into their world, disturbing it or...... Saving it?
