Hart to Hart: Old Friends Never Die

The moneyed, sophisticated Harts -- debonair Jonathan (Robert Wagner) and lovely wife Jennifer (Stefanie Powers) -- are in Hawaii at the private island paradise of a publisher (David Rasche) when Jennifer overhears two guests planning a murder. Jonathan learns it is his old friend Frank Crane (Mike Farrell), now a successful mystery writer, who claims the overheard "plot" was simply writing advice to another party guest. But when, at a masquerade party, a guest dressed like Jonathan is murdered, Jennifer insists it was an attempt on her husband's life.
