Family PlotAlfred Hitchcock's final film was adapted from
Victor Canning's novel The Rainbird Pattern by
Ernest Lehman, who previously wrote the screenplay for
Hitchcock's North by Northwest.
Barbara Harris plays Blanche, a phony psychic, hired by wealthy Julia Rainbird (
Cathleen Nesbitt) to trace the whereabouts of her nephew, who'd been given up for adoption years earlier and who is now heir to a fortune. Blanche's cohort is "investigator" Lumley (
Bruce Dern), who is fully prepared to milk the last dollar out of Julia before locating the long-lost nephew. Meanwhile, we are introduced to elegant kidnappers Adamson and Fran (
William Devane and
Karen Black). The fates of the two couples are inextricably intertwined by the search for the missing heir. ~ Hal Erickson, All Movie Guide
