Moet Meira
Evil voodoo-practicing serial killer Shadow gets executed for murdering pregnant women. Twenty years later the prison Shadow was put to death at has been turned into an experimental women's penitentiary. Tough and fiercely autonomous new inmate Solitaire has some kind of link with Shadow. When Shadow and his lethal shambling zombie minions are resurrected, it's up to Solitaire to stop them.
A psychologist for inmates has knowledge of a secret, experimental brain implant, designed to change convicts' behavior so that they will not remember or repeat their crimes and, therefore, be able to return productively to society rather than remain in an increasing prison population. The procedure, however, suffers some imperfections: Three killers are at it again.
