Until last October, Stamford Hill's highly orthodox Gaby and Tikwah Lock -married for 40 years and who featured in a previous Wonderland film about Hasidic weddings - had never been on a holiday. Their leisure time was spent divided between religious study and domestic duties.

Then they booked themselves a 12 day Mediterranean kosher cruise. Although it tours the same destinations as many ships, this is a cruise like no other. Alongside universal entertainments like belly dancing and a communal jacuzzi, the Golden Iris boasts religious lectures, creative towel folding and couples relationship workshops. The experience of life on board seems to bring a sparkle to many of the marriages it hosts. 'It's like putting a log in the fireplace,' says one woman, 'For the flame not to go out, you have to feed it once in a while.'

Home truths and frustrations emerge from their visits to the cruise ship couples workshop, which Gaby resolves with an unexpected gift for his wife and a little more understanding of Tikwah's exasperation at his domestic shortcomings.
