Someone has been making threatening telephone calls to Joe Mannix, and this mysterious person begins to take shots at him, too -- one of which cuts down Joe's friend Barry Nolan, who runs the photography shop across from Joe's office. That incident brings Joe into a chance encounter with renowned magazine photographer Jill Packard, who eventually begins a friendship with him. But Joe begins to suspect that there's more to the threats than someone who just has a grudge against him, when one of the shots nearly hits Jill, too.
