Lydia and George are a family of four including they're children Wendy and Peter. They live in a futuristic home with vr rooms with crystal walls, the kids got a nursery/playroom that has vr on the walls. So Lydia and George the soon went to the nursery.
They noticed that there were lions eating something but couldn't make it out they were wondering why the children were thinking of killing or something killing something.
They waited a few hours for there children to get back to there house and they finally got back from the carnival and as soon as they got in the door the parents confronted about the room but they denied every thing about it.
Later on they closed the nursery due to him thinking they are lying but they keep herring roars and loud screams so george went back to the nursery and found his wallet with fur bites and blood later on also he finds lydia's scarf with blood on it which leaves him concerned.
But the children crying on the couch and the mom peer pressuring the father to let them have a few minutes so they went into the nursery and told the mom and dad to go in there then slam the door shuts the sound was enought to alert the lions then 3 of them came up to see what the sound was and the lions are going to be full tonight.
The kids turned out to be the main villain of it all locking there parents in a room with nothing to fight with leaving them to get mauled by hungry lions.
