1994 film by Krzysztof Kieślowski

Waking Life is about a young man in a persistent lucid dream-like state. The film follows its protagonist as he initially observes and later participates in philosophical discussions that weave together issues like reality, free will, our relationships with others, and the meaning of life.

It has been nine years since we last met Jesse and Celine, the French-American couple who once met on a train in Vienna. They now live in Paris with twin daughters but have spent a summer in Greece at the invitation of an author colleague of Jesse's. When the vacation is over and Jesse must send his teenage son off to the States, he begins to question his life decisions, and his relationship with Celine is at risk.

Nine years after Jesse and Celine first met, they encounter each other again on the French leg of Jesse's book tour.

A young man and woman meet on a train in Europe, and wind up spending one evening together in Vienna. Unfortunately, both know that this will probably be their only night together.
