An Italian cross-border worker and a Swiss border guard can become friends?

Bussenghi is a cross-border worker who is late to work every day because of Swiss border guard Bernasconi. In a twist of fate, the two nemeses will have to coexist 24 hours a day and, aside from teasing each other about the differences between Italy and Switzerland, they begin to understand and help each other, gradually realizing that they need each other to get out of the trouble they ended up in.
