Read Netflix's official synopsis:
Louise Andersen lives a quiet life on the Norwegian island of Hidra with her partner, Joachim, where she operates a small café. One summer day, their tranquil existence is disrupted by a stranger who insists Louise is not who she claims to be but Helene Söderberg—a woman who vanished from Denmark three years earlier. She discovers not only that she is married but also that she has a young son. Driven to uncover the truth about her forgotten life, Louise leaves Joachim and embarks on a journey to reconnect with her family, seeking answers about the night she disappeared.
