On the third floor of a nondescript warehouse building in Manhattan the "Friday Night Throwdown" is about to begin. Underground fight club fans, gamblers, hipsters and those in the know pack the perimeter of the plywood ring. Through the haze of marijuana & cigarette smoke, the booming bass of the dj spinning dubstep and the shouts of the amped up crowd, the bouts go deep into the morning. That is...until the NYPD arrive.
