The title of this Catalan TV-movie refers to the 'Myth of the Cavern' by Plato: it tells that a prisoners in a cavern only could see the shadows of the free men who walk and talk behind them, so the prisoners believe that all the reality is made of shadows, but one prisoner gets to escape and discovers how is the world, then he returns and tells the truth to the other prisoners, but they think he's crazy and they finish killing him.
The cast of the film has good young actors: Núria Prims, Sara Loscos, Fermí Casado and Jordi Andújar. The director shows a certain talent, but some scenes are little credible and I don't like the final completely. However, it's entertaining, but the Catalan cinema is reduced again to a TV-movie and doesn't have distribution on theaters.
