In the not too distant future, society in London has crumbled. A small group of aristocratic 'vultures' have taken power and oppress the inner city 'rats'. Their rule is violently upheld by the fascistic 'pigs', who guard the walls of the city and refuse to let anyone leave. Amongst growing tensions, a small group of rats emerge to challenge the vultures. They attempt to escape, but are brutally beaten back. In retaliation they ransack the Heaven club, where the vultures spend their evenings drinking themselves sick and sleazing over strippers. During the riot at the heaven club, the youngest rat is kidnapped and killed by the head of the church, the preacher vulture. This is the tipping point that becomes too much for the rats, as they channel the spirit of the young boy, they set about slaughtering the corrupt aristocracy one by one. With power now transferred to the rats, they attempt to leave, but outside the gates they find nothing but the ghost of the young rat, who tells them there is nowhere better to go, that it is the same everywhere, and the only hope for redemption is suicide.
