Following an inspection of the camp by Joe Maplin, Gladys is considered to be the most efficient worker and entitled to a rise. To prove her superiority she sews stripes onto her blazer but other staff members become jealous and decide to add stripes to their uniforms as well. After Gladys' half-brother Gareth has turned up and erroneously identified as a Peeping Tom, Gladys realises that she has been childish and removes the stripes.
