After thirty-five years spent in France, Hèk returns to Laos: in the meantime, his father has died there. With Hé, his brother who remained to live there, on the intervention of their mother who wants to offer him his last trip, he takes the paternal ashes to his native village, in the mountains of the North. It is this journey undertaken by tuk tuk, a flexible but risky means of transport, which brings loss, mourning, healing and perhaps a form of reconciliation within him.
