Youth (2015)

Fred and Mick, two old friends, are on vacation in an elegant hotel at the foot of the Alps. Fred, a composer and conductor, is now retired. Mick, a movie director, is still working. They look with curiosity and tenderness on their children's confused lives, Mick's enthusiastic young writers, and the other hotel guests. While Mick scrambles to finish the screenplay for what he imagines will be his last important movie, Fred has no intention of resuming his musical career. But someone wants at all costs to hear him conduct again.
