Harriet is an X-ray technician earning decent wages for a woman in the 1960s, but involved in a passionless, conventional relationship. When she leaves her old life behind and moves into a boarding house in King's Cross, Harriet meets all kinds of different characters: a struggling artist, a lesbian couple, and a landlady with a penchant for tarot cards. Within the confines of the house Harriet discovers true friendship, supernatural powers, passion, danger, and, most importantly, a child who captures her heart forever.
