"A SWAT team becomes trapped in a tenement run by a ruthless mobster and his army of killers and thugs."
So basically, they scale a 15 floor apartment building and it's a good 1 1/2 hours of them kicking a** and killing each other with guns, knives, machetes, hammers, clubs, bombs, drug lab equipment, walls, broken light bulbs and martial arts.
If you like kung fu and gore movies, you should really check this out. It was a really fun watch that kept me at the edge of my seat. 4laugh
