A Father by Accident (1957)

Against the backdrop of a hot Greek summer and the picturesque island of Poros, impecunious boatmen vie for the attention of the tourists to make a living. As the strict local harbour master tries to inspire the undisciplined and antagonistic boat owners to embrace change, a luxurious yacht, owned by a wealthy orphaned woman from Egypt, arrives, bringing passions, romantic entanglements, and above all, unexpected and equally exciting revelations. Now, someone is about to become a parent. Is he prepared to become a father by accident?
