 The local police are convinced it is an open-and-shut case because Kelvin's driver's license was found in the glovebox, the plates on the car match Kelvin's, and Kelvin's sister, Isold (Julia Stiles), lives on the far side of the tunnel.However, Holt is suspicious because while the body is conveniently unidentifiable, the license is undamaged and Isold, the sole beneficiary of the $1 million policy, is skittish and was not expecting her brother's visit.Isold's husband "Fred" McBride (Jeremy Renner), is unexpectedly cheerful and vaguely threatening, convincing Holt there's more to this case.
