For Simon, a public relations manager at a major aerospace company, lying is a way of life, almost a raison d'être. His family isn’t fooled by his lies and have learned, somehow, to shut their eyes to his nonsense. But when Russian industrialists come to negotiate a contract that could save the struggling aircraft company where his brother also works, Simon's behavior becomes an important issue. Fearing that one lie too many will make everything fall apart, his relatives serve him an ultimatum. The same evening, a strange cosmic event propels Simon into a parallel universe, where all his fabrications seem to have come true.
