Imagine a glass tumbling through the air. Have you ever wondered if it’s feasible to predict the number of fragments it will shatter into? After conducting countless trials, a group of scientists manages to achieve this seemingly unattainable feat. Intrigued by their findings, an enigmatic professor extends an invitation to the researchers to visit his secluded estate to delve deeper into their work. Upon their arrival, instead of a warm welcome from their host, they encounter an unusual replica of the mansion, where ordinary yet astonishing events unfold. The scientists soon realize they are part of a new experiment, one where they must assume an entirely different role: that of the glass in free fall.
