The chaotic journalist Maximilian Glanz is working on his big book that will never be finished, answers letters to the editor of a tabloid newspaper and dreams of escaping to an island and leaving everything behind. His marriage is in crisis. And on the day of his divorce, he meets a new woman in a rear-end collision, who has also just been divorced and with whom he plunges headlong into a new relationship.
