Inspired by the real-life police strike in early-1980s Halifax, the obscure Canadian thriller "Self Defense", a.k.a. "Siege" is a hell of a good time for exploitation devotees. During this period of police inaction, criminal scum are able to do as they please. And so a gang of trouble-making bigots with a "cause" storm into a gay bar and terrorize the customers. Ultimately, almost all the victims end up dead, except for Daniel (Terry-David Despres), who flees for his life. He makes it inside an old apartment building. Initially, the residents are unsure of how to proceed, but soon they decide to shelter Daniel and fight back against the psycho antagonists, who are led by a stone-faced creep named Cabe (Doug Lennox, "Lars and the Real Girl"). And they prove to be decent fighters.
If this hadn't been a "lost" film for such a long time, this would surely have been considered a classic B flick over the decades. Directors Paul Donovan and Maura O'Connell, who went on to do another cult flick, "DEFCON-4", give the story great pace. In fact, the movie is so exciting, quickly paced, and manipulative (these filmmakers know how to push your buttons), that viewers can gloss over any flaws in the narrative and just enjoy the ride. Needless to say, it can get pretty violent, and there's some of the standard "stupid characters doing stupid things" tropes that people expect to find in many movies. But this viewer will say that it hooked him early on, and often delivered the goods.
The cast includes a few actors whom you may recognize from other things: Tom Nardini ("Cat Ballou") as Horatio, Jack Blum ("Happy Birthday to Me") as Patrick (a blind kid with acute hearing), and Keith Knight ("Class of 1984"). Jeff Pustil, who was also in "DEFCON-4", is an amusing highlight as the most aggressive of the bad guys. Daryl Haney is also a standout as the calm and cool Chester; you may better know him as a writer of such things as "Crime Zone", "Friday the 13th Part VII: The New Blood", and "Xtro III: Watch the Skies".
Excellent atmosphere and a haunting electronic score are assets. Worth noting is the tidbit of info that this apparently contains the only known existing news footage of that aforementioned police strike. There is also a priceless, final second twist before the end credits start appearing.
