Oniromance -- Film Description:
"A ringing sound breaks into a woman's sleep. The sinister telephone becomes tangled in its own cord and plunges into dreamlike oblivion. As no one answers the call, nothing will ever come of it, and it will remain an enigma, cloaked in anonymity and nothingness. Film without words."
-- National Film Board of Canada
