Alison)[4] is a 1955 British crime film directed by Guy Green and starring Terry Moore, Robert Beatty and William Sylvester.

[5] It was written by Green and Ken Hughes based on the BBC television series Portrait of Alison which aired the same year.

It contains an empty bottle of Chianti with a British label, "Nightingale & Son" – a firm that does not exist.

She appears at Tim's door and explains that the woman killed in the car crash was not her; when they were driving, Lewis told her that he was on to an international diamond smuggling ring, and that her father was part of it.

She angrily left the car, and assumes that Lewis must later have picked up a hitchhiker, whose dead body was then mistaken for hers.

She has gone to see her father in a hotel to make him tell the truth about the diamond smuggling, but he is terrified, and plans to flee the country.

It turns out that no fewer than four of the major characters are part of the international ring of diamond thieves, and that an independent blackmailer is at work as well.
