At a boutique health-and-wellness resort that promises healing and transformation, nine stressed city dwellers try to get on a path to a better way of living. Watching over them during this 10-day retreat is the resort's director, Masha, a woman on a mission to reinvigorate their tired minds and bodies. However, these nine "perfect" strangers have no idea what is about to hit them.
