A raucous tale of two young doctors enthusiastically tackling the most common ailment known to man – the love bug! Right from the start it’s romance and laughter all the way with Dr Richard Hare (Michael Craig) and his partner Dr Tony Burke (Leslie Phillips) adapting to life at St. Swithin’s Hospital; a country practice and wonderfully entitled ‘Foulness Anti-Cold Research Clinic. In the process, they encounter sultry night nurses, two out of work strippers – Dawn & Leonora (Joan Sims & Liz Fraser) a flirtatious receptionist (Carole Lesley) and luscious Locum Dr Barrington (Virginia Maskell). Needless to say, heartbeats and pulse – rates rush skywards, as love becomes the prescribed tonic. Even the retired surgeon Sir Lancelot Spratt (James Robertson Justice) gets involved and all in spite of a grumbling appendix.
