They own an art gallery, but the financial crisis in the art world has not spared them - they are facing complete ruin. Full of heavy thoughts after a meeting with a lawyer, Gareth accidentally walks into an antique shop, the owner of which asks the girl for a favor - to open a sealed silver box. Gareth agrees, but that was not the case!.. After all, the box is not simple, but with a secret. That same night, the gallery is robbed, and in addition, the criminals steal the box.

But the story begins not here, but in the distant, distant past... It’s not for nothing that Gareth wears a gift from his mother on his finger - a ring with the image of a black swan...
