"One Day One Trouble" follows the turbulent life of Eze, a rebellious teenager notorious for his troublemaking ways. Eze's journey is fraught with fights, vandalism, and chaos, actions from which he is consistently shielded by his overprotective parents, Ngozika and Onyema. Despite their best efforts to keep him out of trouble, Eze's defiance and recklessness continue to escalate, leading to a point where his parents' intervention is no longer enough to save him.
As Eze spirals further out of control, the consequences of his actions catch up with him, culminating in his arrest on a murder charge. Unable to protect him from the severity of his crimes, Ngozika and Onyema must face the reality of their son's choices.
The novel explores themes of parental shielding, teenage rebellion, and the profound impact these have on family and community. It delves into the dynamics of Eze's interactions with key figures such as Mr. Okechukwu, the school principal, his peers Chukwudi and Emeka, and the rival gang member Omenka.
The legal system, represented by the Prosecutor and Justice Egwuatu, plays a crucial role in Eze's fate, while the police, prison warder, and inmates shape his experience in incarceration.
