Max Morlan en zijn minnares, gravin Christina Como, runnen een kosthuis voor modellen. Isabella, één van de inwonende modellen, wordt vermoord door een mysterieus, gemaskerd figuur. Haar vriend wordt verdacht van de moord, maar dan verdwijnt Isabella's dagboek, dat schijnbaar belastend bewijs bevat.
