Bété Bété tells the story of families deeply marked by blood ties. Alkaly Sall and Makhoudia Tall, respectively Guéér and Teug, are lifelong, close friends. A friendship tested by prejudice... Certain considerations surrounding caste make love impossible, such as the youthful romance between Alkaly and Daba Thiam. Diouma, a daughter Alkaly did not acknowledge, was born from this relationship. As a result, Ndiaga Thiam, Daba's very conservative father, harbors a deep-seated anger towards Alkaly. Clinging to her lineage, Marème Sall, Alkaly's wife, refuses to associate with the Gnégnos. Meanwhile, Makhoudia Tall must manage a polygamous household with two wives, Teug and Guéweul respectively. Thus, the Bété-Bété series appears as a reflection of Senegalese society in all its facets.

Codou, Fary, and Baye Zale reflect each day on the journey they have traveled. Behind their lives lies the silent struggle of a mother: Kéwé, widowed far too soon. Illiterate, Kéwé single-handedly bore the burden of the household, taking on numerous odd jobs and sacrificing her dreams to protect and raise her three children. Through her memories, Fary sees and experiences the reflection of this exceptional mother who transformed her tears into courage and her hardships into hope.
