Men like air

19-year-old Finn, recently arrived in New York City determined to even the score with his older brother Jack for abandoning him in the UK in the aftermath of their parents' deaths, wanders into Leo Emerson's gallery.

Leo is haunted by loneliness, unsettled by the contrast between his life and that of his brother-in-law, Isador, who is contented in his faith and his marriage.

Soon, a series of unexpected and interconnected events unfold, changing the lives of all four men, for better or worse.
