Here is a clip from Zal Batmanglij‘s Sound of My Voice, a microbudget dramatic thriller about "a couple who infiltrate a cult in the San Fernando Valley."
Official Plot Synopsis:
Peter and Lorna, a young Silver Lake couple, delve into the underworld of a cult that meets in the San Fernando valley. At the center of the group is an enigmatic young woman named Maggie who never leaves her basement chamber. The members follow Maggie blindly—growing her food, obsessively sanitizing the house, giving her their own blood for transfusions. But why? We follow Peter and Lorna as they smuggle hidden cameras into Maggie’s basement bent on exposing her as a charlatan and freeing the members from her spell.
The movie is playing at SXSW and the producers have released what they are calling a trailer, but is really a one-minute clip. Don't worry, there are not any spoilers in the clip. Check it out below and let us know your thoughts!
