The popular television detective duo from Hart to Hart reunites for another go-around in this made-for-television adventure movie. While the Harts (Robert Wagner and Stephanie Powers) attend a charity auction, they stumble upon an old locket with what may be a picture of Jonathan Hart's long-lost sister. Jonathan may be on the brink of finding his missing sibling -- or he may be a pawn in scheme concocted by some thieves. ~ Bernadette McCallion, Rovi
