When the story begins a young girl who has wandered away from her nanny at a French ski resort is abducted, killed, and buried in the snow. Later, in Venice, the young daughter of Franco (George Lazenby), a popular sculptor, is stalked by a woman in a black veil. Finally, after several near-chances, the girl is grabbed, only to be found later floating in a canal. The police are as arrogant as they are stumped, so Franco, accompanied by his estranged wife, Elizabeth (Anita Strindberg), investigates. As Franco begins uncovering clues, the people he talks to about the case begin to die gruesome deaths.
