Simon is a pathological liar and he cannot continue like that anymore. One day, he is confronted with the reality when disasters as zany and aberrant follow one another. All have one thing in common: they are the incarnation of his many lies. He is now living in a parallel universe where all his lies become reality. Simon will have to face the consequences of the lies he tells others for years, but also the ones – much more destructive – that he tells himself.
