Everyone has their own Chimera, something they try to achieve but never manage to find. For the band of tombaroli, thieves of ancient grave goods and archaeological wonders, the Chimera means redemption from work and the dream of easy wealth. For Arthur (Josh O'Connor), who's just been released from prison after taking the fall for his old crew of tomb raiders, the Chimera looks like the woman he lost, Beniamina.
He starts working with his old crew again to try and find them loot, but he isn’t in it for the money, he craves the love of his life who haunts his dreams. To find her, Arthur challenges the invisible, searches everywhere, goes inside the earth – to find the door to the afterlife of which myths speak. In an adventurous journey between the living and the dead, between forests and cities, between celebrations and solitudes, the intertwined destinies of these characters unfold, all in search of the Chimera.
