Inspired by the work of Italian underground comic book prodigy Andrea Pazienza, Paz! is a 24-hour slice of life of a bunch of students living in a flat in Bologna during the 70's, divided between marjuana, university, girls and political activism.

A police inspector suspects a serial killer is afoot in the university city of Bologna, luring in his victims through online video chats before murdering them and assuming their identity.

Alex, a high-school boy fond of rock and punk music, falls in love with Adelaide, who shares his feelings but doesn't want to get too involved because she will soon leave for studying in America. Alex gets relief in music and his friend Martino who leads what looks to him as a more complete life.
