Dario Argento
4 mosche di velluto grigio

The third and final part of the 'Animals Trilogy' sees master director Dario Argento in familiar Giallo territory. Michael Brandon plays a rock musician who is photographed by a masked assailant stabbing and killing a man that has been stalking him. Later, the masked assailant starts to send Michael Brandon photos of him in the act, and that's where the fun starts.
