Siege is set in a big-city housing development. Retiree Martin Balsam, along with the rest of the building's residents, live in terror of a street gang commandeered by self-styled "king" hoodlum Dorian Harewood. Police lieutenant James Sutorius tries to rally the older citizens to stand up against the younger punks, all to no avail. But when Balsam's lady friend Sylvia Sidney falls victim to the hoods, Balsam takes the law into his own hands--leading to an ironic climax. While it is satisfying to see Martin Balsam giving the arrogant gang leader his due, the made-for-TV Siege clearly sets forth the dangers of vigilantism.
