In a series of raw and honest interviews with lonely people from all walks of life, Dr Sam Carr addresses the issue of loneliness and explores what we can do about it.

In stories of love and loss, of trauma and hope, told from care homes, living rooms, classrooms and kitchens, Carr discovers that while each of their stories is utterly unique, they are all born out of the same desire for human connection. As Carr interweaves these touching and powerful tales with his own personal narrative, he opens a window onto the inner lives of regular people - the forgotten, misplaced or misjudged - who all feel isolated in some way.

Sparking a profound conversation about a universal emotion, which may simply be an inevitable part of life in an increasingly disjointed world, he questions what we can do to build stronger human relationships, and to be a part of something bigger than ourselves.
