I watched 30 mins of the first oneThe story was that the girls were from a family of witches, and the spirit was trying to posseses then because their family promised it a son....
Shits a slow burn, but awesomely told over all the movies....I be zoned in to them shits
That was it lol
It's still the worst series outta all three though
They only got made because they were so cheap to make and easily made money
