A 13-year-old street kid literally sings for his supper, imitating a famous tango singer on the trains running through Buenos Aires's famed Central Station. He dreams of better things for himself and the prostitute he loves, but you know from the first frame that he is doomed. Juan Carlos Desanzo's 2003 drama is purportedly based on a true story, but it's the ghosts of other films about kids living on the margins (Pixote, Central Station) that seem to hover in the background. In sum: solid but thoroughly familiar. In Spanish with subtitles. 93 min.
