My Sister, My Agent follows Mélissa Onana, a passionate and determined football agent, as she manages the career of her brother, international footballer Amadou Onana. More than just a family portrait, the film offers an inside look into the male-dominated and often opaque world of professional football. Mélissa, one of the few women — and even fewer African women — in this field, breaks the mold by asserting her voice and vision. With roots in Senegal and Cameroon, she represents a new generation of African women redefining roles in elite sports. Through negotiations, emotional stakes, and family dynamics, the documentary explores the challenges and strength of sisterhood in a world ruled by men.
