'I Am Not A Witch': Film explores plight of Zambians accused of witchcraft

Cannes, France (CNN)"When I die I will kill you," says an irked woman in one scene from "I Am Not a Witch."

This elderly lady, accused of witchcraft in Zambia, has reached her wits' end with a farmer who's forced her to work his fields. Tired and exploited, she vows to exercise her powers from beyond the grave -- and she's being quite literal.
The line sums up the absurd, paradoxical world of witchcraft. When you've been told you're a witch, forced to live as a witch, forced to act as a witch, you might eventually start believing you're a witch.
