After a successful train robbery, a gang led by Little Walter gets cold feet and needs to get out of London quickly. Little Walter, his moll Bikini and the rest of the gang escape to a Cornish island where they plan to hide out in a monastery disguised as monks. After living the life of a monk the gang splits, some want to leave and spend their loot while others enjoy the benefits of a simple life.—David Bond
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.
