In the Sahara desert, the voice of one of North Africa's greatest singers still echoes. A voice that has engaged and given hope to a forgotten struggle. Mariem Hassan’s life and music have been deeply affected by the ongoing tragedy committed to the Sahrawis throughout the colonial era continuing up to this very day. Her songs have been given comfort and hope, and have been used as a tool in the fight for independence in Africa's last colony, Western Sahara.
The film intertwines the narrative of Mariem's life with her relentless quest for the territory’s liberation. Archival footage and interviews with family, friends, poets, soldiers and fellow musicians paint a vivid picture of a woman whose artistry transcended borders and touched the hearts of those who listened. The title "Haiyu" – meaning to encourage in Arabic – reflects both her rebellious spirit and the collective determination of a people in their ongoing struggle for a free Western Sahara.
