Six train robbers hide from the law in a deserted monastery off the Cornish coast, where disguising themselves as monks proves the perfect way of lying low while carrying on with various criminal activities. But the crooks have a hard task keeping up the pretence when two real monks visit the island - especially since one of the gang is a woman. Comedy, with Ronald Fraser, Barbara Windsor, Bernard Cribbins, Wilfrid Brambell and Davy Kaye.

Having pulled off the smallest ever train robbery, Little Walter and his crew decide to get out of London. The six of them set up business in a disused monastery off the Cornish coast, despite the fact that none of them really qualifies as a monk - least of all Walter's moll Bikini. Bit by bit, the quiet way of life starts becoming a habit.
