Amandine lives in the French coastal town of Calais. At 39, she faces the reality of a terminal cancer diagnosis. As she prepares her family for what lies ahead, she remains full of life, cherishing each moment with gratitude. In the palliative care unit, she encounters Peyo, an extraordinary horse with an innate ability to comfort those nearing the end. Alongside his trainer Hassen, Peyo brings peace to the most fragile patients, and forms an unexpected bond with Amandine. Lyrical yet unsentimental, À demain sur la Lune paints a sensuous, profoundly moving portrait of love, loss and, even in the face of death, gratitude for what life has to offer.
