Samuel is an old hippie musician who settled in Formentera in the 1970s, when King Crimson and other British rock bands frequented the island. There he lives austerely, in a ramshackle house without electric light or unnecessary luxuries, and plays the banjo in a friends' club. Until one day, after many years, he receives the unexpected visit of his daughter Anna and his grandson Marc. Anna, unemployed for some time, says she has had to accept a job in France and is forced to leave her little son on the island with grandfather Samuel.
One Night Stand follows James over the course of a drunken night, as he makes mistakes, meets new friends and reminisces. With a tight cast and a realistic aesthetic, One Night Stand reminds us of hazy nights we've all shared with people we thought we'd forgotten.
Khalil is an uprooted young man who lives small tricks in a border area where industrial buildings and swamps rub shoulders. He regularly visits Jose Ramon, an old man with a troubled past who lives in a house by the river. This house he shares it with his brother Martin, whom he has not spoken to for years. In the swamp, more or less lost souls rub shoulders, without necessarily crossing each other.
Jack is in a rut and unsure what to do with his life. He tries to stay focused and get his life in order, but all manner of distractions get in the way.
Ana is an exemplary girl that has been educated in the 'normality' of a middle-class family. She has never been brave enough to break with all the regulations that her well-led life was supposed to be. The appearance of a double that starts living her life and doing all of her obligations, allows Ana to adopt total anonymity for the very first time. This fact becomes something that she understands as the opportunity to choose the life she wants without giving any reason to anybody, as the way to find total freedom and also happiness. Who is this double, where she comes from and why she appears are questions that I am not interested in answering in the film. This is just the starting point that is accepted as the motor that helps Ana to have the courage to fight for her own existence. Ana tries to make her own runaway possible breaking with everything, looking for her own limits, living a life opposed to whatever everybody expected from her.
