A series of five new films

On 21 July 1972 Mrs Avril Mitchell and her 16-year-old son Alan set out for France. In 24 hours both would know if they had achieved their lives' ambition. They had with them £250, scraped together from raffles, charity walks and dances - money that would all go to pay those experts essential to the success of 'The Crossing.'
Before sunrise on the next morning the attempt began. Conditions were poor. It was cold and there was a thick fog. Throughout that day fortunes changed by the hour. As evening approached Alan Mitchell's strength drained away. It looked as if the attempt might fail.
