OMG just wasted 2 hours of my life for what NOTHING !!! First, what is she dying of per se? I thought it was to end her life not save her life. Brad was money hungry the entire time...was that his wife or girlfriend or friend!!! Secondly, Everyone dies except Grace who by a miracle has some medicine to revive her. She was in a cult apparently they killed her husband to save her life. Maybe she was the leader was her second husband trying to kill her. She look at her son in disgrace wonder did she hear him talking about the money. Brad leaves his girlfriend to die and they kill him for what because she gave the order or he seen too much ? If I could get some answers would be great upset about not getting one answer from this movie and the fact all of her kids die and she gets all of the monies seems like she put the cult up to it...
