Every choice we make has a consequence.
Even the ones made in other realities.

After the death of her beloved Gran (the last warden of this reality), Emma begins to experience terrifying lapses as she unconsciously crosses the threshold into other realities – realities in which she has made very different choices. Even dangerous ones. Meanwhile across the world, a hard-living hipster named David has found a way to jump from one reality to another, randomly intersecting and falling in love with a disinterested Emma. In a fight against sociopathic supernatural beings hellbent on destroying all, Emma and David must join forces to collapse the bubbles of the multiverse into one in an attempt to hold their reality together.
