Inspired by the exploits of New York's Guardian Angels, which began as a band of streetwise young people who formed an anti-crime subway patrol and went on to gain a national reputation and units in major cities around the country, this film unites three New York City youths as leaders of a citizens' patrol tackling gangs terrorizing merchants and local citizens.

A repressed Catholic NYPD detective uncovers a netherworld of deranged faith, alien insemination and his own unholy connection to a homicidal messiah with a perverse plan for the soul of mankind.
