Fool Night

In the distant future, earth is covered by thick clouds and deprived of the warm rays of sunlight. Natural plants have all but withered, leading to low levels of oxygen everywhere.

However, humans have developed a technique to transform people into plants to produce a small amount of oxygen that allows mankind to keep surviving. In this world, everyone must decide: Will they live as humans in a bleak and uncertain world, or abandon their anguish to embrace a new life as plants?
