In the quantum realm...

Six travelers across time encounter a mysterious city and are forever changed. Is it a place of lost souls, a refuge for healers, a bridge into an unknown world? The narrator Enya discovers cylinders of ancient stories told in the voices of the travelers and each time she listens, the borders of her reality alter. The voices ask, who is she now?

A star warrior goes into the city on a planet where souls disappear. A healer sings the songs in his heart but to his village he is a demon—he seeks the walled city of his dreams as sanctuary. A modern physicist looks at the city as a world of high towers, filled with corruption, where power and money are gods. A young Chinese couple fear imminent attack by marauders and escape into the desert and mountains to find the crystal city they believe is their refuge.
