Anyway, in an overcrowded future there is a one-child policy. One man has a ‘seven-twins’ and names them after the days of the week, so there you have both titles explained.
The man hides his daughters in his massive apartment and thinks of an elaborate plan to give his daughters a wee bit of freedom: they get to get out on the weekday they are named after. Of course this cannot go well for eternity.
The sisters are played by Noomi “The Girl With The Dragon Tattoo” Rapace. Inside their apartment the girls have their own style and personality, outside they are all the same person. Once the authorities find out about them, the film turns into an alright sci-fi action thriller. Too bad that the film ends with rather boring drama and what is even weirder: the governments policies have a logic, but the overcoming of them is presented as a victory.
“What Happened To Monday” is descent thriller with a bad end.
