Year 2050 a deadly bacteria ends humankind and destroys the world as we know it. All living things die as a result of this bacteria that emerged from a bio-chemical laboratory. But there is one living organism that survived all these - legumes.
The vegetable possesses a chemical compound called lectin that is resistant to the killer bacteria but alas when humans discovered its efficacy against the bacteria it was all too late. Not even bean lovers could have been saved by the common variety bean.
As decades and centuries passed the world is re-populated by mutant legumes which included beans, nuts and peas. Factions emerged and wars ensued. The world is divided between good and evil. The nuts lead by their villainous leader Dr. Leopoldus Knut want to rule the world but the beans won't have any of it.
An aging but clever computer programmer Beanie Sanders leads a secret group of revolutionaries called The House of Beanions and they are out to thwart Dr. Knut's every dastardly move to rule the world.
