While her father is out, Margaret slips down into the basement with her brother to see what has been going on. If it wasn't for the living plants that seemed to be acting as if they were humans, Margaret wouldn't have ever gone down again- unless there was a reason to. She tries her best to please her father, but one day he makes them both soup- a greeny, slimy goo that could well be something as horrible as Monster Blood. Someone is at the door, and so while her father answers it, she chucks the goo down the drain. She knows that she has to find out what is going on- even if it ends up into a tale of suspense and tension, that builds up with horrible images, making Margaret realise what is going on. It could all end up with Margaret making a terrifying decision, that could change the family forever.

This tale reflects how important families are to everyone, and the uneasyness of the family- not knowing what is happening, in the Basement- heightens the tension and suspense in the book, and the film.
