"There has to be a non-crazy explanation for how we can see things happening forty six years ago." In 2016, Jess finds herself hiding in a locker and hears knocking on the side she didn't come in from. On the other side of it is the winter of 1970, two girls who found each other in the worst of times, and a horrible memory that was supposed to stay lost. Love and hate. Black and white. Some secrets should stay locked away. They can still beckon. They can still haunt us.
