A private eye investigates the disappearance of a businessman who seems to have lived a seedy second life. The investigation leads to a prostitute who may have had unsavoury dealings with the fellow and who seems to being stalked.

Director Alan J. Pakula squeezes the maximum suspense out of a thriller where, by modern standards, not much happens aided by a terrific turn from Fonda and a low key one from Sutherland.
