In the film "Father's Warning," Joshua, a middle-aged man, remains unmarried, citing his concern for his sister Bella, who is trapped in a toxic and abusive marriage with Bill. Joshua's father, MZEE AGABA, urges him to marry, believing it will bring stability to his life. Against MZEE AGABA's wishes, Joshua marries Sandra, a former prostitute whom MZEE AGABA disapproves of due to their past encounter in his friend's office. As Joshua navigates his new marriage, he believes Sandra can change for the better despite MZEE AGABA's warnings. Meanwhile, Bella continues to suffer at the hands of Bill's abuse, but societal norms and her father's reluctance hinder her from seeking a divorce. However, a pivotal moment occurs when Bill publicly assaults Bella for talking to a male friend at work, prompting her to finally leave him and file for divorce.
