As they a finishing stealing her purse and ring, a projectile from the sky pierces a nearby car. No one else notices as fireworks are going off all over town. When the gang leader crawls into the car to look for additional valuables, he encounters a strange ape. It scratches him, so he chases it down to kill it. The gang proudly take the dead corpse to their apartment block. They are beset by large, black creatures with mouths full of glowing blue teeth that seemingly have singled out the gang. They are unaware that their clothes are tainted with pheromones from the one they killed that provoke the alien attack. Now the gang members are running for their lives and struggle to defend their block from an alien invasion of these blind wolf-apes. It is only when they hide in a marijuana grow room with UV growth lights, that the pheromone contamination becomes visible. Gang leader Moses is most strongly affected. He needs to devise a plan to draw the wolf-apes to a location where he can kill the entire group at once.
