Doctor in the House S10E01 - Sins of the Father

Over twenty years have passed since their student days. Dick is now Professor of Surgery with rich wife Emma and daughter Rebecca, a militant union leader among the medical students, Paul is a thrice-divorced Harley Street consultant and Duncan married to Loftus's daughter Geraldine. Whilst perusing a photo album to discuss the guest list for Sir Geoffrey's upcoming birthday party, the three doctors find a picture of former nurse Dorothy Sheridan, who dated them all. When Rebecca introduces her friend Justine, Dorothy's daughter, each wonder if they are her father - as does colleague Lionel Snell.
