The Lovers Arrive (1956)

They say all work and no play makes Jack a dull boy--and the successful soap factory owner, Potis--is exactly like this; a dull husband who is married to his job. Little by little, Potis has let his work ruin his marriage; however, with the arrival of his wife Lela's cousin, Mina, things are bound to take a turn for the unexpected, as an ingenious romantic scheme behind his back will get the neglectful spouse right where they want him. Before long, the girls' plot combined with the rampant imagination of Potis' fantasist best man, Markos, will have the industrialist green with jealousy--so jealous and distrustful, that no man is above suspicion; especially the charming gentleman and upstairs neighbour, Spiros Argiriou. Is Potis' wife safe when the lover arrives?
