Rene Vaubois, head of French Intelligence and, surprisingly, also an old friend of Modesty Blaise, is kidnapped by a brutish gang leader, known appropriately as the Wild Boar, who is out to milk him of all his knowledge for use in extortion. In a most unusual manner, Blaise learns of the capture in an abandoned village on Corsica and she and Willie Garvin head there to rescue Vaubois.
