Yasmin, an Indian teenager from zanzibar, is married by her parents to Bwana Raza, an Indian trader who is much older than her. When the couple moved to Mombasa, Yasmin soon grew tired of the unhappy life she led to her side and fled. Returning to the city, she is chased away by her family and will find refuge in Mwajuma, a Swahily in the popular neighborhood of Ngamb'u, who introduces her to Swalibian life and her pleasures. Yasmin then discovers friendship and love when she meets Denge, a young intellectual who has returned from Russia and engaged in the anti-colonial struggle. With his fellow wrestlings, he entered the country censored prayers and newspapers and participated in operations intended to overthrow British power. Between Denge and Yasmin was born a love as strong as it was impossible. At the same time, Bukheti, a young man who loved Yasmin in Mombasa, decides to leave everything to find her and convince her to marry her. When a policeman zealously in the colonial government discovers Yasmin's past and ties to Denge, he pushes her to betray her lover. In the face of these difficult choices, which path will Yasmin choose to take? Denge, ready for all sacrifices to free his country from the colonial yoke, renounce Yasmin's love?
