Scott Barnes is a former ad executive turned social worker living in Miami. He is also a recovering alcoholic who stopped drinking after accidentally killing his son in a drunk-driving accident. One of his cases is Tommy a street kid who has been selling crack for an organization called the Youth Incentive Program. Barnes is unaware of this, but suspects something when Tommy buys expensive gifts for his mother and sister. He also notices the YIP tattoo on Tommy's arm. Tommy is kidnapped by YIP and forced to package crack into vials in an abandoned building with many other children. After Tommy does not come home for several days, his sister calls the morgue and they inform her he is dead. Barnes goes to the morgue to identify Tommy, but discovers it is not him, although he sees the YIP tattoo on the corpse. While trying to find Tommy, he witnesses a shootout where one of the gunmen has a YIP tattoo. He goes to see Sgt. Palco, who tells him about YIP. Barnes, convinced Tommy has been kidnapped by YIP, then talks to the head of the narcotics division, Lt. Ortega who tries to convince him to stay away from the gang. While looking for Tommy in the streets, Barnes notices the YIP henchman James and follows him to a nightclub. There, he meets his old girlfriend Jackie and is shocked when he sees her speaking to James. After sleeping together, Barnes learns Jackie is a lawyer for YIP and tells her he wants to get into the organization to rescue Tommy. After some consternation, Jackie tells Barnes that YIP is willing to induct him as a member. Barnes goes to meet with Carlos, the head of YIP, who wants him to help expand the organization into the suburbs. James then shows him around the organization and leads him to the warehouse where Tommy is being held. Tommy tries escaping and is taken to the Madison House, an abandoned factory where members of YIP who commit transgressions are killed. Barnes finds out about this from one of Tommy's friends. Barnes is taken to the Madison House and sees Tommy. He then goes to see Lt. Ortega, who tells him if he interferes further, he will be charged with conspiracy to distribute narcotics. One of Carlos' henchmen sees Barnes enter the police station and informs Carlos, who now believes him to be an FBI agent. Barnes goes to see Jackie and discovers that she has been killed by Carlos' henchmen, who then attack him. Barnes escapes but is quickly kidnapped by the henchmen. He is taken to the Madison House and thrown into an elevator pit filled with alligators, but gets caught in the wiring and manages to escape. Barnes finds Carlos and the two have a fist-fight just as the police raid the building. Barnes finally manages to punch Carlos down into the elevator pit, killing him. The police arrest the rest of the YIP members and Barnes drives away with Tommy in a police car.
