When a group of students manage to complete Thomas Edison's unfinished "spirit phone" that allows communication with the dead, they are brought to the spirit world by an ancient Incan priest. There they meet historic figures such as Albert Einstein, Buddha, and Friedrich Nietzsche and learn the hidden truths of the cosmos, heaven, hell, and God.
