Art of the Devil (2004)

Boom, pregnant from an affair, is told by her lover to leave him and his family alone. Enraged, she goes to a witch doctor and has him use black magic against her ex-lover and his family. They all die in suspicious manners. Just when Boom thinks everything is over, a woman claiming to be her lover’s secret mistress claims his inheritance and moves in to his house with her 4 children. Not long after that, unexplainable things happen to the family and, one by one, they begin to die.
