The last city left on Earth, an absurdly overpopulated dystopian metropolis surrounded by a malevolent forest inhabited by a terrifying creature that feeds off human sacrifices. Population is strictly controlled, unsanctioned procreation punishable by death and self sacrifice rewarded. A hopeless romantic, Matylda, discovers that she is unlawfully pregnant after an awkward one-night stand with Vincent. They are forced to make a choice between the rules of the city, and the creature in forest.
