Women Have to Play Games to Get Babies Back

by Anonymous

I'm looking for the name of this film that starts off with a woman in a bath, and she finds out that someone has removed her unborn baby from her stomach.

She then discovers that there are other women in this place that have had their babies taken from them, and that they have to play a game of killing the other women in this place.
It shows that their are keys that have been placed in their stomachs that they have to remove to open the doors of the cots that their babies are in.

In the end, one woman survives and finds out that its a place where they find out whether the baby is strong by making its mother hunt to survive, so that the people keeping them hostage sell the baby to other families.
