A doctor is trying to develop a cure for a childhood syndrome lending towards hyperviolence. Due to his mistake, his daughter was inadvertently infected with the disease from a contaminated needle. Now, the doctor uses a cursed silver syringe to suck out the essence of a small gland that controls violent behavior from unwilling prostitutes, and inject it into his daughter to give her a temporary cure. Unfortunately, the process renders the donor hyperviolent as well. A friend of Micki's is grabbed by the doctor and submitted to the treatment. Trying to locate her friend, Micki herself is kidnapped and subjected to the process.
