A dramatic contemporary story with elements of a political thriller and a strong ethical message. On a foggy, smoggy winter day, a group of terrorists hijacks a Prague bus with four passengers and the driver. They declare that they will hold the hostages until the government and parliament meet their demand to change the air pollution law. The drama of the hostages lasts one night and two days, during which a series of dramatic situations unfold. The plot takes us into the attractive world of high politics and the homes of ordinary people who are directly affected by the hijacking. Gradually, the film's fundamental question comes to the fore: Is it possible to resort to extreme measures, i.e., violence, in order to achieve environmental goals? Is it possible to achieve a cause that benefits everyone through terrorism?
