Inspired by Austrian playwright Arthur Schnitzler's "Round Dance", the director Fernando Meriles and the screenwriter integrate the modern and ever-changing spiral narrative in the original work into a story. through the connection of the characters in the play: they come from different countries and cities to tell vivid, suspense and touching love legends in the 21st century. The story begins in Vienna, and the film beautifully weaves a simple but fascinating narrative from Paris, London, Bratislava, Rio, Denver and Phoenix.
