On a suburban London street in the mid-1970s, a young man collapses and later in hospital dies, only to find himself travelling in an entirely different dimension. There, he encounters unimaginable worlds of horror and bliss on a journey that takes him to the very source of life itself. As doctors resuscitate him, he returns to the living, but with a desperate need to reconcile his experience with a world that is no longer familiar. This leads him down unexpected paths on his search for an understanding of the nature and, most of all, the location of the uncharted worlds beyond this life. Based on a true story.
