In this silent film, early roots of sci-fi magic are given to us in the form of a scientist who invents a ray that makes people caught in its beam fall asleep where they stand. With magical and wonderful shots of a Paris long gone, it is the adventure of a group of unaffected people who, with their sudden freedom, play the game of mice while the cat is away. With a narrative that sways toward a moralistic stance on the principles of fair play and responsibility, this little science fiction fable can still be as poignant today as when the magnificent views were first shot from the dizzying heights of the Eiffel Tower.
