Radiant psychologist Katerina has to confront her worst suspicions as she accompanies Yannis, an early once-respected doctor, to identify the victim of a tragic car accident at an off-season seaside resort.

Arcadia follows radiant neurologist Katerina and Yannis, a former well-respected doctor, who are heading off to a deserted seaside resort. Silence spreads in the car as they travel across sandy dunes in a windy autumn, matching the less-than-pleasant occasion: Yannis had been called to identify the victim of a tragic accident at the hospital of the small town. When the local policeman informs them that the victim's vehicle had plunged over the parapet of a stone bridge and leads them to the morgue, Katerina sees her worst suspicions confirmed. Together with Yannis, but also on her own nightly excursions to a mysterious, rustic beach bar called Arcadia, they begin to put the pieces of the puzzle together, revealing a haunting story of love, loss, acceptance and letting go.
