What Happened to Monday (known in several territories as Seven Sisters) is a 2017 dystopian science-fiction action thriller film directed by Tommy Wirkola and written by Max Botkin and Kerry Williamson.

In the near future, overpopulation has resulted in a strict one-child policy, enforced by the European Federation's Child Allocation Bureau.

The next day, Tuesday retraces her steps and discovers Monday got the promotion they were up for and met their co-worker Jerry at a bar.

facility, Tuesday meets presidential candidate and head of the bureau, Nicolette Cayman.

Learning the agents used Tuesday's severed eyeball to bypass the building's retinal scan, the sisters suspect Jerry may have sold them out.

agents arrive and kill Saturday after she tells her siblings Monday was dating Adrian.

Admitting that she can not survive on her own, Friday sacrifices herself by blowing up their apartment to allow Thursday to escape and rescue Monday.

Meanwhile, Tuesday and Adrian broadcast Thursday's video footage of the incineration, leaving everyone at the event shocked.

The now-traumatized crowd directs its attention on Cayman, who angrily confronts Thursday before her bodyguards pull her off.

The Child Allocation Act is abolished, and Cayman faces the death penalty for her actions.

The film was originally written for a man, but director Tommy Wirkola had always wanted to work with Noomi Rapace.

[6] Wirkola was inspired by films such as Children of Men and Blade Runner due to their realism and world building.

Its critics' consensus says: "This high-concept sci-fi action thriller will make you stress-eat all the popcorn while Noomi Rapace (times seven) goes on a murderous spree to find out What Happened to Monday, but it may still leave you hungry in the end.

[12] Jessica Kiang of Variety called it a "ludicrous, violent, amusingly dumb sci-fi actioner", remarking that although it is full of plot holes and Rapace's characters are thinly characterized, it is likely to become a cult film.
