Following the death of their friend and loyal valet Max (Lionel Stander) Jonathan and Jennifer (Robert Wagner and Stefanie Powers) decide to go to Montreal as they had planned with Max. It is there they hook up with friend and novelist Lady Camilla (Joan Collins) and her latest beau Ronnie Scott (Jeff Kaake). But things are not as they seem as Ronnie is with someone else and is up to no good. When Jonathan and Jennifer accept a time piece left to them by Max they also find themselves drawn in to Ronnie's scheme.
"Hart to Hart: Two Harts in 3/4 Time" was the first of these made for TV movies which was made following the death of Lionel Stander and you have to question whether it was the right thing to do. Whilst Stander's failing health had seen him playing a lesser part in these TV movies his presence completed them and without him it just didn't feel right. In fairness I would imagine for Wagner and Powers making "Hart to Hart: Two Harts in 3/4 Time" was not easy after the loss of a friend and it lacks the energy and fun that you have come to expect from a "Hart to Hart" movie.
Having said all that the actual storyline this time which sees Jonathan and Jennifer in Montreal and drawn in to a mystery involving a designer clock, murder, blackmail and of course scheming feels weak. I am taking a guess the writers manipulated a story which was already written to work in the death of Max but it makes it convoluted, okay more convoluted than you would normally get from a "Hart to Hart" movie. The knock on effect of this is that whilst this "Hart to Hart" movie features Joan Collins it is a waste of her talents as the story seems to have been switched around and cutting her part down.
What this all boils down to is that "Hart to Hart: Two Harts in 3/4 Time" is a weak movie even when you take into account it is a "Hart to Hart" movie. But I would imagine that the circumstances with the death of Lionel Stander making it an incredibly hard movie to make for Robert Wagner and Stefanie Powers who lack their usual energy and chemistry.
