Alla ricerca del piacere (1972) by Silvio Amadio
aka: Amuck!

Greta Franklin (Barbara Bouchét) plays with more than fire, when she secretly follows the footsteps of her best friend Sally, who mysteriously disappeared while working as a secretary at a writers house. Shortly after her arrival at the pretty venecian island, she gets thoroughly introduced to the delirious habits and delights of her charming employer Richard (Farley Granger) and his chameleonesque wife Eleanora (Rosalba Neri), who seems to be possessed by some rather exotic faibles and talents.
