The Jamboree -

The grand finale of the film, a mafia-style family cult, ‘The Mutineers’, celebrates the marriage of one of their sons to the daughter of the Mayor. They play a game similar to Russian Roulette where the bride attempts to shoot a girl dressed in a crow costume who the cult has kept locked in a human-sized birdcage outside their compound. During the reception the titular Knights arrive and massacre the Mutineers.
