Two robbers embark on a daring heist at a cell phone store, wielding a gun to fulfill their mission. As they attempt to flee on their motorcycle, a mishap occurs, leaving the bike dangling from a pole, far beyond their grasp. In a desperate effort to evade the police, they dash through narrow alleys and break into the home of Ma Jiaqi, a quadriplegic woman, where they threaten her with violence. However, Jiaqi, confronted with their intimidation, boldly challenges them into action, shocking the would-be criminals as they falter in their resolve.
Meanwhile, Ma Xianyong, Jiaqi's brother, endures a brutal altercation with his former employer. He recently unearthed a gun at a construction site, only to discover it has mysteriously gone missing. Burdened by a mountain of debt, unable to provide for his daughter’s high school tuition, and struggling with loans, Xianyong finds himself oddly drawn to the unfolding robbery. In a moment of desperation, he confronts Gao Ming, a bankrupt real estate agent whose apartment he purchased, using the gun to intimidate him. Yet, Xianyong's actions do not go unnoticed by Ming's son, Gao Xiang, who also shares a bond with Xianyong’s daughter.
Among the chaos is Bobby, a hefty young man mistakenly labeled as one of the robbers, who works at a nearby spa. Xianyong tracks him down, mistakenly believing he's involved, and subjects him to torment. Ironically, Bobby himself had been a victim of the robbery and leads Xianyong to the seedy spa rife with illegal activities. However, chaos ensues when police conduct a raid, resulting in Bobby's arrest, much to the dismay of his daughter, who chastises him for the trouble he finds himself in.
In an unexpected turn of events, Jiaqi asserts her authority over the robbers, directing them to follow her orders and perform tasks for her. To their embarrassment, it is revealed that the phones they pilfered are nothing but plastic replicas. The incident catches public attention, and emotions run high as a news report about the theft plays on Jiaqi's television, igniting outrage from viewers.
The situation escalates when the robbers take Jiaqi to the rooftop, where tensions boil over. Flashbacks reveal the tragic circumstances that left Jiaqi in her current state following a car accident involving Xianyong. As he shows up at Jiaqi's door to discuss matters, a protest unfolds; frustrated clients of Ming demand compensation for their losses. In the midst of this uproar, Xiang seizes a gun, seeking revenge, but accidentally shoots Xianyong instead. This leads to confrontations between Xiang’s peers and the criminal elements present.
Xianyong finds himself hospitalized due to the shooting incident. Yet, the narrative does not end there. The robbers, unexpectedly, show up at the hospital in an ambulance where Xianyong confronts them, wielding the fake gun. The atmosphere thickens as Guangsheng, one of the robbers, reveals a real firearm. In the ensuing pandemonium, Guangsheng shoots Xianyong, prompting police intervention. Amidst the chaos, Xianyong, wielding his fake gun, manages to spray water at the officers, ultimately leading to their surrender.
In the climax of this turbulent tale, a poignant reconciliation occurs between Xianyong and his daughter, highlighting the complexities of family ties amidst the harrowing events surrounding them.
