Dr Nookey 'discovers' a medical slimming cure while in exile on a far off island. He returns and goes into partnership with Ellen Moore.
In the meanwhile Dr Carver has been sent out to this far off island and when he returns to find Dr Nookey in a Harley Street practice he, with the help of Dr Stoppige, set out to expose him as a fraud.
Great jokes and action from the Carry On team.
