Cross Country (1983)

After a woman is found butchered in her New York apartment, suspicion falls on her estranged husband, an ad executive who has suddenly left town on a cross-country road trip. He takes along a beautiful girl he met in a bar and a drifter he picked up along the way. A cop sets out after the husband, but he's more interested in shaking him down than bringing him back.
