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.
