Mamie (2005)

In a sprawling house, the elderly Granny lives alone, cared for entirely by her devoted granddaughter Sabrina, whose attention is wholly focused on her weakening grandmother. But are Sabrina's motives truly selfless? What does she want from Nico, her lover, who comes to visit one night? They are about to discover that beneath the frail and vulnerable exterior of Granny lies something else entirely.
