It is the second animated series by Zerocalcare after Tear Along the Dotted Line, which features the same characters, and it can be considered a standalone sequel to the previous work.

The series received generally positive reviews from critics, with praise towards its animation, story and emotional weight.

The story revolves around the opening of a refugee shelter in an eastern neighbourhood of Rome, which has exacerbated tensions between neo-Nazis and local anti-fascists, including Zero.
