In June 2013, a group of 800 people occupy an abandoned cinema in the centre of Barcelona to screen a documentary. They rename the old building after a young woman who took her own life two years earlier: Cinema Patricia Heras. Who was Patricia? Why did she end her life, and what does Barcelona have to do with her death? That is exactly what this illegal action sets out to make known: the truth about one of the worst cases of police corruption in Barcelona, the dead city.
