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.
