The team are invited to investigate the officers' mess of a military base in Bedfordshire, once home to monks and nuns of a 14th century Gilbertine Order. It was an experiment in unisex living.

John Ette from English Heritage monitors proceedings, and they are also joined by historian Richard K. Morris and osteoarchaeologist Margaret Cox. Robin Bush tells the miraculous tale of the Nun of Watton.
