The beautiful and sensitive Sol (Ana de Armas) dreams of true love. Months ago, however, the young woman's dreams were tragically shattered after she contracted AIDS from her partner. As a result, the 21-year-old looks for relationships with people who are also HIV-positive. When Dani (Martiño Rivas), also heartbroken, contacts her, her new happiness seems perfect. But Dani has a secret: he is not HIV-positive at all, but a journalist looking for AIDS sufferers in order to draw an article from their experiences. However, his feelings for Sol are not fake. David Menkes' romantic drama is based on Jordi Sierra I Fabra's novel “A little bit of April, a little bit of May, all of September”, which in turn was inspired by a real story.
