After her divorce, Ava and her friend come to Niagara Falls, trying to start a new chapter in life and simply escape from her own memories. But a chance meeting with Wyatt, an attractive and too-perfect stranger, quickly changes her sense of security. His attention seems sincere, and their rapprochement seems natural, but cracks gradually appear behind this perfect image: strange coincidences, indirect hints, the feeling that her life has long been familiar to someone. When the romantic story begins to take on a disturbing hue, Ava realizes that trusting this man means risking everything, and escaping from the past can turn into a trap from which there is no easy way out.
