From IMDb:
"The film is divided into six segments. (1) "Pasternak": While being on a plane, a model and a music critic realise they have a common acquaintance called Pasternak. Soon they discover that every passenger and crew member on board know Pasternak. Is this coincidence?"
"(3) "The Strongest": Two drivers on a lone highway have an argument with tragic consequences."
