Conversations between two people alternating with pictures of the "˜Massa Critica' (Critical Mass) move- ment. The bicycle is one of the greatest inventions in the history of mankind: it integrates a mechanical device with human propulsion, it is the turning of energy into equilibrium; it is a symbol of resistance and faith in the future. "˜Massa Critica' consists of urban cyclists who want to fight a society completely overrun by motorcars.
