There's no way to tell just from the name. It could be a self - published book that tells a local true story about a killer soup. On the other hand, it might be an independent movie that was inspired by a real incident related to a soup that had some sort of deadly impact. It really depends on who created it and what their medium of choice was.
The term 'killer soup true story' is quite ambiguous. It could be based on a true story. If so, perhaps there was a case of food poisoning from a soup that had been tampered with, or maybe there was a murder where the poison was administered through a soup. On the other hand, it could be a made - up story using the 'true story' label for marketing purposes. We would need to look into more details about the story itself, like who wrote it, where it came from, and if there are any real - life references associated with it to really know if it's truly a true story.
I'm not sure exactly as there's not much information given just from the title. But it could be about a soup that had some sort of harmful ingredient in it, like poison, which led to some sort of disaster or crime.
The 'killer soup based on true story' could be a really interesting and disturbing concept. Maybe in the story, the soup was part of a plot in a small community. For example, someone made a special soup with rare or dangerous ingredients that had unforeseen and deadly consequences. It could also be that the soup was used as a means of revenge in the true story, and the events that unfolded around it are what make it a story worth telling.
I have no definite knowledge. It's possible that there are elements of truth in it, or it could be entirely made up. We might need more background or author statements to know for sure.
I'd say no. There's no widespread knowledge or evidence suggesting that 'Killer Soup' is a real story. It could just be a creative idea or part of a fictional tale.
Financial gain could also be a motive. For instance, if there was an inheritance or some sort of valuable asset at stake, and someone wanted to eliminate the competition, they could use the 'killer soup'. Another motive might be jealousy. Maybe someone was jealous of another person's relationship or success, and decided to use the soup as a way to harm them.
