Four stories, four people who know nothing about each other, while sharing the walls of the same building, which contains not only episodes of everyday life but also a universe of solitude and missed opportunities.
Andrea, a broken-hearted cook; Jessica, a career woman looking for the perfect man; Philipp, handsome boy and gymman who does not want to settle down; Antonio, a melancholy elder man who survives with memories.
One day, the three young tenants meet and decide to leave together for the summer holidays. What they will live will be an unexpected, intense, passionate and overwhelming experience, at the end of which nothing in their lives will be more like before.
(Next 9 is the name of the building where the characters are living. The 3 young people will have a tree side relationship during beach holidays and when back they will explore the possibility to continue like that.)
