In a bleak near‑future where the world’s population has surged beyond control, a draconian one‑child law enforced by the Child Allocation Bureau dictates who may live. The regime’s relentless monitoring forces families to hide any extra offspring, turning ordinary households into secret fortresses of survival. Within this oppressive landscape, a modest suburban home shelters an extraordinary secret: seven identical sisters, each named after a day of the week, who have been trained to exist as a single person in the eyes of the state. The sisters share their lives in a tightly choreographed routine, swapping identities, wigs, and stories so that only one of them ever steps outside the confines of their shared existence.
Monday—the eldest and the unofficial leader—embodies the group’s disciplined unity, while her siblings Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday each bring a distinct temperament to the collective. Their father, a quiet architect of their covert operation, has instilled in them a code of absolute secrecy, knowing that a single slip could mean total annihilation. The sisters’ daily meetings become a whispered council where personal hopes, fears, and the minutiae of a fabricated life are exchanged, forging an intense bond that borders on both family and singular identity.
Against this backdrop of surveillance and scarcity, the Bureau’s chief enforcer, Nicolette Cayman, looms as the embodiment of the regime’s relentless authority. The sisters’ delicate masquerade must navigate bureaucratic scrutiny, societal pressure, and the ever‑present threat of discovery. The tone of the story is tense and claustrophobic, a blend of dystopian thriller and intimate character study, inviting viewers to wonder how far a tightly knit family will go to protect one another when the world insists they are illegal.
