In the year 2073, the world grapples with a severe overpopulation crisis, leading to the implementation of a draconian one-child policy by the Child Allocation Bureau (C.A.B.). In a poignant twist of fate, when Karen Settman gives birth to identical sisters, only the eldest is allowed to remain. Her father, Terrence, names each of the sisters after the days of the week and meticulously trains them to live as a single entity, preserving the secret of their existence. The sisters meet daily to share their experiences and information, adhering to a strict rule: only one can venture out into the world at any time.
To disguise their identity, they employ a clever system of wigs and makeup to mask any identifying traits. Terrence, who understands the grave risks they face, often reinforces the importance of their bond and the repercussions of disobedience. However, the tension mounts when Thursday breaks this crucial rule and, in a devastating incident, injures her finger, leading to Terrence having to remove the same part from all the sisters, starting with Monday.
As the years pass, the sisters manage to maintain their deception without raising suspicions. One day, as Sunday returns from her job at the bank, she witnesses C.A.B. agents detaining a child amidst public outcry. The siblings, watching the distressing event unfold on their screens, engage in a heated discussion about their future. Thursday contemplates the possibility of surrendering themselves, dreaming of a time in the future when she could live openly, and pursue her own path. However, Monday, ever the responsible elder sister, insists on the necessity of their unity, reinforcing their pact to continue living under the veil.
The following day, Monday endeavors to present herself as Karen but finds herself caught in the web of office politics, with the ambitious Jerry hinting at blackmail after she secures a promotion. Her absence at their daily meeting sends alarming ripples through the sisterhood, triggering Tuesday to investigate her disappearance, ultimately leading to a shocking revelation. Monday’s dealings with C.A.B. prove to be a perilous game of survival, and soon, what started as a deceit spirals into a betrayal of epic proportions.
As C.A.B. agents zero in on the sisters, they navigate a web of deception where loyalties are tested and lives are lost. Through a series of action-packed confrontations, starting with a harrowing showdown where Sunday meets a tragic end, the weakened sisterhood must find strength to persevere. The sisters fight back, driven by the need to uncover the truth as they grapple with their intertwined fates.
Amidst the chaos, alliances shift and betrayals unfold. In a desperate attempt to save one another, the sisters face the brutal world enforced by the C.A.B. that threatens to tear them apart permanently. With tension rising, Adrian, a C.A.B. agent with a complicated connection to the sisters, is entangled in their fight for survival.
This gripping narrative reaches its zenith when Thursday, with the help of Adrian, schemes to infiltrate C.A.B. headquarters, uncovering the dark realities of their society. As the sisters pursue their path to redemption against overwhelming odds, a treacherous game of power and identity ensues, leading to heartbreaking confrontations that reveal the true cost of survival.
At the climax of their struggle, the sisters are forced to confront each other in a dramatic showdown, leading to devastating consequences that challenge their bonds and redefine their identities. With an irreversible choice made, the fallout reshapes their lives forever. As the dust settles, the remnants of their struggles herald a new beginning—a chance for renewal in a society where the unthinkable had once reigned supreme.
In the end, their journey leads to the repeal of the Child Allocation Act and the dawn of a new hope for their future as they embrace the next chapter of their lives, forging their identities anew.

Unravel the ending of What Happened to Monday (2017) with our detailed explanation. Understand the final scenes, character fates, and unresolved questions.
In the final scenes of What Happened to Monday, after a tense struggle with the Child Allocation Bureau (CAB) and the revelation of their brutal practices, Monday’s sister Thursday manages to expose the truth by broadcasting evidence of the CAB’s atrocities. During the chaos, Monday is shot and mortally wounded, but it’s later revealed that her twins are safe, growing in an artificial womb.

Despite their moral victory and the lifting of oppressive rules, the world remains overwhelmed and unsustainable, implying that humanity’s problems are far from over and that the planet’s future remains bleak. The ending suggests that while some individuals might find hope or redemption, the broader environmental and societal collapse persists, leaving the viewer with a sobering vision of an overburdened planet.
Discover the spoiler-free summary of What Happened to Monday (2017). Get a concise overview without any spoilers.
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.
