For a drop of happiness... some suffer, endure, remain silent.

Karpenisi, 1944. The sounds of the German conquerors' weapons have just subsided. In that August, two boys are born, Fokas and Giannis. The first, the fruit of a forbidden love that had to remain hidden at all costs. The two children grow up together, like siblings. The bonds that unite them are stronger than the secrets that separate them.

Until the fateful moment comes when they both fall in love with the same woman, and she, despite the commands of her heart, succumbs to the pressures of her parents, choosing the one who can provide her with the most material goods. On the night of their wedding, two sworn enemies are born. From then on, the labyrinth in which everyone, innocent and guilty, will be trapped unfolds before them, dark and ominous. Destructive lies will lay the foundation for their future and the future of their children.

Twenty years later, Ariadne, the daughter of Fokas, will fall in love with the wrong person. It is the moment when the myth begins to unravel, exposing their hidden mistakes and passions, bringing everyone face to face with the truth. Until the end...

For a drop of happiness... Only then do mouths open, hearts unlock, and secrets come to light, guiding their lives to where they were always meant to be, forever and ever.
