The Lotus Eaters (1972)

They say that once you have eaten from the lotus plant - you will never want to return home. To outward appearances Erik and Ann Sheppard (Ian Hendry and Wanda Ventham) are typical English ex-pats running a bar on a far-flung Greek island. But appearances can be deceptive - this is an arranged marriage of a different sort - with roots in international espionage. Stefan Gryff gives a great performance as the omniscient local police captain.
