To explain this film is very simple, it is A film about different moral and ethical viewpoints of people. When put in a predicament to choose who gets to live or who gets to die. A lot of people would say they would never kill a pregnant lady or an old person or a kid, they chose different individuals of different ages, races, backgrounds and allowed everybody to show their true state when placed in this type of situation. So this movie is about morals, ethics rather you believe in individualism, Absolutism, consequentialism, Egoism and other moral and ethical theories. Not only which one you believe in or believe you are, but the movie shows your hidden moral/ethical being. To make you think am I really the type of person I think I am? and when put in a situation will I really do the good I think I will
