A man takes his longtime girlfriend Louise to Idaho with him. They are going to Idaho because the man owns a small car dealership there. Since accepting the offer of a local buyer, the man has received a far better one. Now, the man hopes to anger the buyer enough that he'll back out from the deal. Louise and the man are not married, though they've spent a great deal of time together. Louise is a successful attorney, and she asks the man why he doesn't just let this deal close, since he has no guarantees from the other interested buyer. At some point during their drive, the man wonders aloud why they don't just get married. Louise looks away and is quiet. They arrive in Rigby, Idaho, where the dealership is located. Louise and the man enter a room with an escrow agent named Brent Colby, and the buyer, Oren Johnson. The man selling the dealership tries to anger Oren, but he ends up coming off as a fool and closes the deal with Oren. Louise is unimpressed by the man's display of bravado. Louise and the man start the drive home, and somewhere along the winding highway, a car begins to follow them closely. The man pulls over to let the car pass, but the car stays behind them. They continue driving, unnerved, and the car continues to follow closely. At a sharp curve, the man presses hard on the accelerator and then, once around the corner, turns off his lights and pulls into a scenic turnoff. The car appears behind them and, out of control, shoots over the side of the road and into the river below. They look over the edge of the road to see the car is submerged. After their road trip, the man and Louise talk by phone irregularly. Eventually their calls stop altogether.
