LA MORTE VIVANTE (1982)
dir. Jean Rollin
The eternal slumber of the once vital 20-year-old Catherine Valmont is disturbed when a violent tremor shakes her underground crypt. Now the much lamented, delicate and oblivious Catherine is enticed to dwell in the world of the living tethered to the place she used to live, summoning pale memories of her beloved blood-sister Hélène, who remains her only link to this earth except for that vague, yet overwhelming rabid desire for innocent fragrant blood. Sooner or later, the dumbfounded Hélène will encounter once again her solitary dark sister who is longing for her in silence, but is the cryptic Catherine the person she once knew or has she become a grim and soulless monster?
