Kim and Aggie travel to Ealing, West London, to look at the standards of cleanliness and issues of hygiene facing Britain's hospitals. Ealing Hospital has been publicly criticized in the past for its levels of sanitation. But during the last 18 months the hospital's Chief Executive, Fiona Wise, has worked tirelessly to raise standards of cleanliness. Over three months, the hospital opened its doors to the scrupulously clean Kim and Aggie, allowing them free rein to visit all departments to examine cleanliness levels and tackle any problems in their own unique style.
