This episode features a range of patients, some very wealthy but others whose care is paid for by foreign governments or in some cases by charity. Interwoven with these moving and surprising stories are tales of everyday life on Harley Street - a flower delivery service, a cycle courier delivering medical samples, as well as an interview with the director of the Howard de Walden estate, which owns almost all the property in the area and allocates leases to doctors wishing to practice here.
