THe story starts in the house with George, and his wife, LYdia. They are discussing the nursery and introducing us to the house. The house is very futuristic and advanced.
They enter the nursery and realize they are now at a veldt in africa. It feels very real and Lydia starts to freak out. They exit the nursery and talk about how real it felt.
George finds his bloody wallet in the nursery. Mr. McClean shows up and finds lydia's bloody scarf. They hear familiar screams from the nursery and Mr. Mcclean tells them to shut it down.
They finally power off the nursery and decide that they are gonna go on a vacation, away from all the tech. The kids just want one last moment in the nursery. Lydia convinces George to let them have one more moments in there.
The kids call up the parents to come here. When the parents get there, they don't see the kids. The kids lock the door behind them and lock them in. The parents realize why the screams sounded so familiar. They lions close in on them and presumably eat them.
The kids sit in the nursery and have a picnic while watching their parents be eaten. Mr. McClean shows up to get them and he is clueless they were just murdered.
