It starred Ego Nnamani, Francis Agu, Bob-Manuel Udokwu, Mildred Iweka, Kunle Bamtefa, and Richard Mofe Damijo Set in Lagos, the story focuses on the Haatrope family, the enemies determined to destroy their business and legacy, and their friends and associates. Checkmate is seen in the show's opening credits, where a chess player's king is directly attacked by an opponent's pawn, making escape impossible. The show's opening and ending theme is Ron Goodwin's main theme for the 1964 war film 633 Squadron, and the main character - Ann Haatrope - is loosely based on Queen Amina of Zaria. Plot Ann Haatrope (Ego Nnamani, and briefly Yomi Davies) returns to Lagos from America with her brother Richie (Bob-Manuel Udokwu) to discover the family's infrastructure and investment firm, Haatrope Investment, is on the brink of collapse due to older brother Benny's (Francis Agu) incompetence caused by alcoholism and sloth. Benny is also violent towards his wife, the equally nefarious Tonye (Edyth-Jane Azu) who does not approve of her husband's siblings living under their roof, and is particularly horrid towards Nana Kofo (Ruth Osu), the elderly Ghanaian housekeeper who has served the family for years. With their father Richard Sr. critically ill back in America and Richie lacking experience, Ann is determined to restore the company's reputation and fight off competition from scheming rivals, most notably the unscrupulous Segun Kadiri (Richard Mofe-Damijo) who bears a long-time grudge towards the Haatropes. He blames them for his descent into childhood poverty following his mother's death, and has sworn vengeance. Ann's best friend, banker Ada Okereke (Mildred Iweka), is married to school teacher Nduka (Bimbo Manuel), but the couple face several problems including their class difference (Ada is the daughter of wealthy parents while Nduka is from a more humble background), Nduka's jealousy, and Ada's inability to conceive. Ada is later revealed to be an osu which infuriates Nduka's mother (Obiageli Molube) who refuses to accept an 'untouchable' as her daughter-in-law, and is on a mission to break up the couple. Nkemji (Uche Mobuogwu), an uncouth teenager from family friend Peace Fuji's village, is brought into her son's home as his new spouse but Nduka, who would later work for Haatrope Investment, rejects her as he loves his wife dearly.
