1537. On the day when Hayreddin Barbarossa and his pirates spread death among the inhabitants of Paleochora in Kythera, no one notices the deadly attack of a man on his pregnant lover. A dagger once held by great warlords and kings is thrust into her womb, opening an endless bloody cycle through the centuries.

2020. Two of the world's top treasure hunters, Raul and Sienna, known as Wolf and Moon, are hired by two different art collectors to find the deadly sword. As they embark on the hunt, the story of the sword and the heavy curse it carries are revealed. While its discovery seems like an unsolvable puzzle, an unexpected voice from the past becomes the key in Sienna's hands, leading Raul to the one-way path of alliance with her. In a breathtaking adventure from Greece to Italy and back, the two heroes go from hunters to the hunted. With death lurking at every step, the passion that arises between them becomes at times a hindrance and at times a bright beacon on their path. As they delve deeper into the vortex of this quest, it seems increasingly impossible for the Moon to spread its serene light in the sky and for the Wolf to turn his howl into a song.
