With even his defence counsel convinced of his guilt, a female psychiatrist tries to prove that the police and legal system have made a mistake.

Phillip Bellamy, a leading barrister, tells his wife, psychiatrist Anne Dyson, about his most recent case defending a young man, Harry Jukes, who has apparently shot a policeman on a country road and been found by police still holding the gun.

At the policeman's suggestion, Harry asked a couple in a car parked in the copse nearby for help, but disturbed at being caught in an illicit tryst, they refused and drove away.

The woman is ready to co-operate, but the man panics and in trying to get away crashes into a tree, killing himself and severely injuring his girlfriend, who then makes a useless statement.

The Monthly Film Bulletin wrote: "Basically the old race-against-time story, alternating visits to the condemned cell with sequences of amateur detection, Mix Me a Person has been done up contemporary – which roughly means that the nightclub of a few years ago has been replaced by guitars and espresso in Battersea.

The unsettling effect extends to more familiar locales, and neither Donald Sinden, who gives an uncommonly irascible performance, nor Anne Baxter, saddled with lines of whose implausibility the actress seems all too well aware, can be called at ease.

Adam Faith likeably goes through the part of injured innocent; and the film tries – though how tentatively and ham-handedly – to show that it is with it by a night car ride, nouvelle vague style, and some 'realistic' police and prison detail.
