A young man (Aidan Gillan) arrives in the midst of London's Soho. He's from Belfast, he's anxious and he looks like he's running away from something. Then, by chance, he meets Grace, a prostitute who happens to come from Belfast too. A connection is made and, for a brief time, she seems to offer the chance of a new future.

Scotland Yard investigate when a woman, apparently the estranged wife of a London painter, is murdered with a shotgun in rural Surrey at the same time as the artist's striking model with her long black hair disappears.
