A second rate policeman (Clint Eastwood) is given the job of transporting a witness (Sondra Locke) who is a prostitute with a degree, to testify at a mob trial. However there are all manner of people and corrupt police trying to stop them. There is no great plot and this is not the best chase movie, but Clint Eastwood gives a typically good performance and this is one of Sondra Locke's better performances.
