In a municipal swimming pool, a group of regulars meets every day, sharing their rituals and solitudes without truly knowing each other. In this refuge "down there", each comes to keep the world's tumult at bay. The water eases burdens, gestures repeat, and tiles pass by in a reassuring routine. Among them is Alice, a retired factory worker in the early stages of dementia. Here, everyone looks out for her. But one day, a crack appears at the bottom of the deep end, heralding others: those of her memory. Between the tangible world and her daydreams, between reality and forgetting, Alice slips toward an elusive elsewhere, upending her family and questioning how our society manages vulnerability and how it supports non-productive individuals.
