Siege

A bunch of selfrighteous bullies want to set some "new rules" in town while the police in Halifax (Nova Scotia, Canada) are on strike. They try to scare all the gays and lesbians in a bar, but by accident the owner of the establishment is killed, and the leader of the bullies then decides to execute all witnesses. One guy, though, escapes and takes refuge in an isolated block of flats. The young tenants in the house refuse to hand over the survivor, and the bullies then decide to get rid of all the residents in the house. This turns out to be not so easy, because the young people in the house barricade their apartments, set up traps and arm themselves in order to fight back, and this inevitably leads to more bloodshed and killings.
