A telephone number dialled in error could prove the downfall of a ruthless criminal gang in this gripping Merton Park thriller from versatile British director Vernon Sewell. Featuring Italian star Lisa Gastoni and noted character players Peter Reynolds and Paul Whitsun-Jones, Wrong Number is presented in a brand-new transfer from the original film elements in its as-exhibited theatrical aspect ratio.

Before he can phone his boss to confirm that the job has been successfully accomplished, the elderly Miss Crystal mistakenly dials the same number and hears a girl ask if it is Angelo speaking. The next day, seeing the newspaper headlines, Miss Crystal realises she may have a valuable clue – but can she remember the incorrect number she dialled..?
