When a team of particle physicists conducts an advanced test at the Edison Laboratory in Milan, Ohio, they break through the boundaries of time and space. Their initial enthusiasm crashes when they realize they have released a mysterious and malevolent force.
Fifteen miles away, James and Joshua, identical three-year-old twins, frolic near the woods at a local campground. Unaware they are the only ones who can see the anomaly, they approach the spherical Shimmer. Joshua steps into the mist and disappears.
Through the years, James continues to encounter the Shimmers – some good…some terrifying. Determined to find his missing sibling, James partners with his younger brothers Matt and Mark, and his lifelong friend Bob on a mission to find Joshua and bring him home.
Their exploration sets up a life and death struggle – and the future of the world as we know it hangs in the balance.
