Summer on the island of Poros. Babis, a single father, takes his teenage twins, Konstantinos and Elsa, on a sailing trip aboard the family boat. Days unfold in golden rituals - swimming, sunbathing, new friendships. But beneath the warmth, something stirs: the twins cross paths with Anna, their birth mother, who left them as infants - and whom they don't recognize. For Babis, the encounter reopens old wounds. For the siblings, it marks the beginning of a tender, quietly seismic journey into adulthood, identity, and the unspoken ties that shape us.
