Brian Stimpson is a British school headmaster obsessed with punctuality. When invited to give a speech in Norwich, he misses his train. He gets Laura, one of his pupils, to give him a lift. Halfway there, he meets Pat, a former girlfriend, and gets her to drive (because Laura doesn't have a licence, and she she won't let him drive). Taking a wrong turning, their car gets stuck in a field, leaving Brian covered in mud.
Brian wanders into nearby monastery to get help. A monk offers him a bath, while another rescues the car with a tractor. While Brian is bathing, Pat drives away. Brian and Laura follow, Brian dressed only in a monk's habit. Will he get to Norwich in time to deliver his speech (and will he be dressed suitably)?
