Such a Long Absence (1985)

With her catatonic older sister, Alexandra, smitten by an unjust fate and confined to a bed, Aggeliki becomes her guardian angel. More and more, as the unresponsive woman gets trapped in a silent world, Alexandra's family, her aunts, and especially, her cruel mother, strongly believe that, under those circumstances, a public mental institution is now the only solution. But, when they finally succeed in locking Alexandra away in a psychiatric hospital, Aggeliki summons up the courage to rebel and to take matters into her own hands. Can Aggeliki alone defend their already fragile freedom?
