Aitana, Pierrick, Rita and Jorge are all in their twenties and all look for ways to make their nights in the city of Madrid a little less lonely. Aitana is a sweet girl trapped in a men’s body; Pierrick is a cute French gay; Rita doesn't much care about her partner, Carolina, and walks through life with no expectations; Jorge is trapped in a relationship with no future: the one he has with Maria. Set against a background of drugs, sex, multiple partners and differing sexualities, Longing Nights follows the individual stories of these young people. A candid portrait of four relationships highly loaded with eroticism from beginning to end. Four stories told without no borders between fiction and reality.
