Yesterday strangers, today inseparable soulmates. But separate they must in just a few hours. Jesse and Celine are making every moment count, pouring as much living as they can into the time before sunrise. Ethan Hawke and Julie Delpy play twentysomethings who meet on a train in Europe, sense a connection and explore after-hours Vienna together. The people, places and allure of the city become their sudden itineraries. Love is their destination. On the way there's the mutual sharing of hopes, jokes, dreams, worry and wonder. It's a day to linger in their memories. And a valentine to young love forever.
