In a world where families are limited to one child due to overpopulation, a set of identical septuplets must avoid being put to a long sleep by the government and dangerous infighting while investigating the disappearance of one of their own.
In a not so distant future, where overpopulation and famine have forced governments to undertake a drastic One-Child Policy, seven identical sisters (all of them portrayed by Noomi Rapace) live a hide-and-seek existence pursued by the Child Allocation Bureau. The Bureau, directed by the fierce Nicolette Cayman (Glenn Close), enforces a strict family-planning agenda that the sisters outwit by taking turns assuming the identity of one person: Karen Settman. Taught by their grandfather (Willem Dafoe) who raised and named them - Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday - each can go outside once a week as their common identity, but are only free to be themselves in the prison of their own apartment. That is until, one day, Monday does not come home.
The title changed to "Seven Sisters" during post-production but when Netflix bought the film, it was changed back to "What Happened to Monday", its original title. See more »
