Pierre has been married for 15 years and has two kids. He still loves his wife and is fulfilled in his role as a father. Overall, he’s a contented man. Until one evening, he meets Elsa.

They go their separate ways without swapping phone numbers, preferring to let life take its own course. As the line blurs between how they imagine their relationship and what has actually happened, their fantasies start to mingle with reality
