Claude Brasseur plays a villain on the run from both the police and the mob. Good atmosphere in the Paris by Night, including deserted factory, Les Halles market and an empty theatre.

On the quiet campus of the remotely-located SouthWestern University, something strange is happening. All of the dogs in the area, once loyal, gentle pets, are now banding together in wild packs and hunting down their former masters. Could the strange transformation have anything to do with the secret government experiments being conducted in the school's physics laboratory? More importantly, can the dogs be stopped before it's too late?
