Led by the gentle and imposing Leonard, the assailants tell 7-year-old Wen and her doting dads, Andrew and Eric, that prophetic visions have shown them that the world will soon end, and that only their family can save it - by killing one of their own.
With limited access to the outside world, the family must decide what they believe before all is lost. Shyamalan dazzles here with his gift for taking the kinds of ideas that once comprised the plots of pulp magazine stories, anthology television, and B movies and turning them into high art.
Save your family or save humanity. Make the choice.
