In this drama from Italy, Diego (Alessandro Gassman) and Shary (Michela Cescon) are a wealthy couple who have rented a luxurious summer house by the sea, which they're sharing with their friends Matteo (Massimo Poggio) and Francesca (Maria de Medeiros). Life is easy until the arrival of David (Thyago Alves), Diego and Shary's handsome son in his early twenties. While everyone likes David, his presence brings out a sense of rivalry and unspoken longings among both couples, and when their friend Leonard (Christo Jivkov), a psychiatrist, arrives, his theories about why so much has changed since David showed up does little to ease anyone's mind. David's Birthday (Il Compleanno) was the second feature film from writer and director Marco Filiberti, following the controversial 2003 release Poco Piu Di Un Anno Fa (aka Adored: Diary Of A Porn Star); the film received its world premiere at the 2009 Venice International Film Festival.
